Answer:
The perimeter of the triangle can be expressed as 5x + 18.
Step-by-step explanation:
Perimeter of an object is the sum of the length of its sides.
For the required triangle, we have;
length of the base = x
length of the second side = 3x + 9
length of the third side = x + 9
Perimeter of the triangle = length of the base + length of the second side + length of the third side
= x + (3x + 9) + (x + 9)
= x + 3x + 9 + x + 9
= 5x + 18
The perimeter of the triangle can be expressed as 5x + 18.

Answer:
2 [tex]\frac{1}{20}[/tex]
Step-by-step explanation:
for question a)
It would be easier if you converted these to improper fractions (currently it is in the form of a proper fraction)
to convert to improper fraction, you would multiply the denominator (bottom no. of fraction) by the whole number , then add that with the numerator (top no. of fraction) and put the whole thing over the denominator.
E.g.
7 [tex]\frac{1}{4}[/tex] = 7x4 + 1 = 29
Thus, improper fraction would be [tex]\frac{29}{4}[/tex]
do same thing for other one
thus , [tex]\frac{26}{5}[/tex]
now,
[tex]\frac{29}{4}[/tex] - [tex]\frac{26}{5}[/tex]
however, you can't do this as the denominators are not the same, so multiply them by a number which would give the a common denominator (20 would be the best option for common denominator)
[tex]\frac{145}{20} -\frac{104}{20}[/tex] = [tex]\frac{41}{20}[/tex]
convert back to mixed number
2 [tex]\frac{1}{20}[/tex]
Answer:
Step-by-step explanation:
a) Step1 : write in improper form
Step 2 : Find least common denominator
Step 3: Find equivalent fractions and then subtract
[tex]7\frac{1}{4}-5\frac{1}{5} = \frac{29}{4}-\frac{26}{5}\\[/tex]
[tex]= \frac{29*5}{4*5}-\frac{26*4}{5*4}\\\\=\frac{145}{20}-\frac{104}{20}\\\\=\frac{145-104}{20}\\\\=\frac{41}{20}\\\\=2\frac{1}{20}[/tex]
b) Keep Change Flip method
[tex]4\frac{1}{4}[/tex] ÷ [tex]2\frac{1}{5} = \frac{17}{4}[/tex] ÷ [tex]\frac{11}{5}[/tex]
[tex]=\frac{17}{4}*\frac{5}{11}\\\\=\frac{85}{44}\\\\=1\frac{41}{44}[/tex]

Which of the following isolates r correctly?
4r - 6 = 2(n + 3)
Answer:
r = 1/2n + 3
Step-by-step explanation:
Are there answer choices to choose from?
This is how you would isolate the r:
4r = 2n + 6 + 6 so 4r = 2n + 12
Solve for r by dividing both sides by 4 so r = 1/2n + 3
Answer:
-2=2n+6
2n=2-6
2n=-4
n=-2

When the function f(x) is divided by 4x−5, the quotient is 3x^2 −x+3 and the remainder is −2. Find the function f(x) and write the result in standard form.
Answer:
f(x) = 12x³ - 19x² + 17x - 17
Step-by-step explanation:
We can the numerator by multiplying the denominator by the quotient, and then adding the remainder.
We're given a denominator of 4x - 5
a quotient of 3x² - x + 3
and a remainder of -2
so the original numerator is:
(4x - 5)(3x² - x + 3) - 2
= 12x³ - 4x² + 12x - 15x² + 5x - 15 - 2
= 12x³ - 19x² + 17x - 17
Let's test that by dividing it by 4x -5 with long division:
[tex]\ \ \ \ \ \ \ \ \ \ 3x^2 - x + 3\\4x - 5\overline{)12x^3 - 19x^2 + 17x - 17}\\.\ \ \ \ \ \ \ \ \ \underline{2x^3 - 15x^2}\\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ -4x^2 + 17x\\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \underline{-4x^2 + 5x} \\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 12x - 17\\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \underline{12x - 15}\\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2R[/tex]
That matches, so we know our answer's right, and:
f(x) = 12x³ - 19x² + 17x - 17

Answer:
The area of triangle VZX is 210 cm^2
Step-by-step explanation:
Here, we want to get the measure of the area of triangle VZX
From the given diagram, we have two explicit triangles making up triangle VWX
These are triangles VWZ and VZX
By adding the areas of both triangles, we can get the area of VWX
Mathematically, the area of VZX is the difference between the area of VWX and VZW
To get the area of VZW, we can use the formula for the area of a triangle
We have this as 1/2 * base * height
base = 35 cm and height = 28 cm
The area of VWZ is 1/2 * 35 * 28 = 490 cm^2
The area of triangle VZX is thus;
700 cm^2 - 490 cm^2 = 210 cm^2

fufghtykkoooogtthhgfthhyfrhjrtffujfjgeetjkabout what percent of gyms in shanesville have fewer than 56 gym members
Answer:
25%
Step-by-step explanation:
About 25% of gyms in Shanesville have fewer than 56 gym members.
The correct answer is option (2).
What is interquartile range?"Interquartile range = Q3 - Q1"
What is percentage?"It is a number or ratio that can be expressed as a fraction of 100."
For this example,
Q1 = 56
Q2 (median) = 64
Q3 = 70
So, the interquartile range is,
⇒ 70 - 56 = 14
Let 'x' be the number of gyms in Shanesville have fewer than 56 gym members.
so, the percent of gyms in Shanesville have fewer than 56 gym members would be,
⇒ 14 / x = 56
⇒ x = 14 / 56
⇒ x = 1/4
⇒ x = 0.25
The percentage of 'x' would be,
⇒ 100 × 0.25 = 25 %
Therefore, about 25% of gyms in Shanesville have fewer than 56 gym members.
The correct answer is option (2).

Answer:
x=29.4
Step-by-step explanation:
To help find the sides of a triangle, I use SOHCAHTOA.
SOH - CAH - TOA
S=O/H ([tex]Sine=\frac{opposite}{hypotenuse}[/tex] )
C=A/H ([tex]Cosine=\frac{adjacent}{hypotenuse}[/tex] )
T=O/A ([tex]Tangent =\frac{opposite}{adjacent}[/tex] )
Let's find x first. We know 2 parts of the triangle: the adjacent leg, and the angle that is opposite of that.
So it would be tangent (tan).
opposite = 17
adjacent = 30°
Plug these numbers into the calculator and you should get your answer.
[tex]\frac{17}{tan(30)} = 29.44486372...[/tex]
x=29.4
Try to do y on your own and let me know if you have any questions!

A tank has 120 gallons of water and is being drained at a rate of 12 gallon each second. Another tank has 100 gallons of water and is being drained at a rate of 14 gallon each second. Which equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water? Multiple choice question.
The equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water is 120-1/2x = 100-1/4x
What is meant by equation?There are many different ways to define an equation. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
Various kinds of equations: Algebraic math equations include the following.
Equation with Lines;
More than one variable may be present in a linear equation. An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation.
Equation in QuadratureThis equation is of second order. At least one of the variables in a quadratic equation needs to be raised to exponent 2.
Cubic FormulaA third-order equation is this one. At least one of the variables in cubic equations needs to be increased to exponent 2
Given ,
tank 1 = 120 - 1/2x
tank 2 =100 - 1/4x
Therefore 120-1/2x = 100-1/4x
So we can conclude that the equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water is 120-1/2x = 100-1/4x
The complete question is: A tank has 120 gallons of water and is being drained at a rate of 12 gallon each second. Another tank has 100 gallons of water and is being drained at a rate of 14 gallon each second. Which equation could be used to determine x, the number of seconds, when the two tanks have the same amount of water? Multiple choice question.
120x + 1/2 = 100x + 1/4
120 + 1/2x = 100 + 1/4x
120x - 1/2 = 100x - 1/4
120 - 1/2x = 100 - 1/4x

Plssss help———What is an exponent and how do you solve it? 4-5 sentences :)
Answer:
[tex] {5 }^{2} [/tex]
that is an exponent
Step-by-step explanation:
an exponent is a number at the top right corner of a bigger (physichally) number. Exponents can also be said "to the power". for example 5 to the second power, or power of 2. this just means that instead of multiplying 5 x2 you are multiply 5 x itself the amount of times the exponent tells tou for example 5 x 5 (since my exponent is 2) is 25. so 5 to the second power is 25. and if it said 5 to the power of rhree i would have done 5x5x5 =125
