Step-by-step explanation:
Rectangle is similar to rectangle . Which proportion can be used to find the value of x?
If rectangle is similarity to rectangle, to find the value of x we use proportion (c) 5/12 = 2/x.
What is called similarity of shapes?When applying a scale factor, similar shapes are enlarged versions of one another.
All of the matching angles and lengths in related shapes are equal and in the same ratio.
If two figures share the same shape, congruent corresponding angles (which means the angles in the same places of each shape are the same), and identical scale factors, they are said to be "similar figures."
Given that rectangle EFGH is similar to rectangle JKLM, it means the corresponding sides of both rectangles are similar, and as such the ratios if the corresponding sides of rectangle EFGH and rectangle JKLM would be equal.
Thus, EF/JK = FG/KL
Since, EF = 5; JK = 12; FG = 2; and KL= x, therefore, the proportion to use in finding x would be:
5/12= 2/x

Step-by-step explanation:
Answer:
[tex]56.8x+39.2[/tex]
Step-by-step explanation:
First, you must distribute the 2's to the expressions:
2(4.4x+7.6) = 2(4.4x) + 2(7.6) which is equal to 8.8x + 15.2 and;
2(24x+12) = 2(24x) + 2(12) = 48x + 24

what is angle ?In Euclidean geometry, an angle is a shape that is made up of two rays, known as the angle's sides, that meet at a point in the middle known as the angle's vertex. Two rays may combine to form an angle in the plane where they are positioned. When two planes collide, an angle is also created. They are referred to as dihedral angles. An angle in plane geometry is the possible configuration of two rays or lines that share a termination. The origin of the English term "angle" is the Latin word "angulus," which meaning "horn." The vertex is the point where the two rays, also known as the sides of the angle, converge.

Given that k(3) = 0 and h(- 4) = 0, for the polynomial h(x)=x^4+2x^3-13x^2-14x+24
Write h(x) in factored form and write down all the real roots of the polynomial.
The polynomial h(x)=x^4+2x^3-13x^2-14x+24 in the factored form is (x−1)(x+2)(x−3)(x+4). The real roots of the polynomial is x= 1, x = 3, x = -2, x = -4.
What is a polynomial function?
In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable.
The polynomial function is -
h(x)=x^4+2x^3-13x^2-14x+24
Divide the polynomial h(x) by (x-1) -
(x^4+2x^3−13x^2−14^x+24)=(x−1)(x3+3x2−10x−24)
Divide (x^3+3x^2−10x−24) by (x+2) -
(x−1)(x^3+3x^2−10x−24)=(x−1)(x+2)(x^2+x−12)
Solve the quadratic equation x^2+x−12=0.
x^2+x−12=0
x^2+4x-3x-12=0
x(x+4)-3(x+4)=0
(x+4)(x-3)=0
So, (x−1)(x+2)(x^2+x−12)=(x−1)(x+2)(x−3)(x+4)
Therefore, x^4+2x^3−13x^2−14x+24=(x−3)(x−1)(x+2)(x+4) .
The Rational Root Theorem tells us that if the polynomial has a rational zero then it must be a fraction q/p, where p is a factor of the constant term and q is a factor of the leading coefficient.
We can see that p(1)=0 so x=1 is a root of a polynomial h(x).
Divide the polynomial by (x-1) -
(x^4+2x^3−13x^2−14x+24)/(x-1)=(x^3+3x^2−10x−24)
Divide (x^3+3x^2−10x−24) by (x-3) -
(x^3+3x^2−10x−24)/(x-3) = (x^2+6x+8)
To find the last zero, solve equation x+4=0
x=-4
Therefore, the real roots are - x = 1, 3, -2, -4.

The inequality can be written as g * 37.5 >= 120.
What is linear inequality?
A linear inequality is a mathematical statement that describes a relationship between two or more variables that form a half-plane when graphed. The equation of a linear inequality is in the form of "ax + by < c" or "ax + by > c" or "ax + by <= c" or "ax + by >= c", where x and y are variables, and a, b and c are constants.
An inequality that could be used to determine the minimum number of gallons, g, of gasoline Darla would need to drive 120 miles to her brother's house is:
g >= 120/37.5
This inequality states that the number of gallons, g, must be greater than or equal to the number of miles Darla needs to drive, 120, divided by the number of miles per gallon her car gets, 37.5. This is because Darla wants to ensure that she has enough gasoline to make the trip, and she may not want to risk running out of gas on the way.
Another way to write this inequality is
g * 37.5 >= 120
This inequality represents the same meaning as before, we multiply g by the number of miles per gallon the car gets, 37.5 and it should be greater than or equal to the distance she needs to travel which is 120 miles.
Hence, the inequality can be written as g * 37.5 >= 120.

The next term of the sequence is 512.
What is Geometric Sequence?A geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r.
Given:
Sequence :2,8, 32, 128,...
As, the sequence is a geometric progression which can be expressed as
[tex]Tn = ar^{n-1[/tex]
Here, a is the first term = 2
n is the number of terms = 5 (next term is the 5th term)
r is the common ratio = 8/2 = 32/8 = 4
So, [tex]Tn = ar^{n-1[/tex]
[tex]T_5[/tex] = 2[tex](4)^{5-1[/tex]
[tex]T_5[/tex] = 2 x [tex]4^4[/tex]
[tex]T_5[/tex]= 2 x 256
[tex]T_5[/tex]= 512
Hence, the next term is 512

An investor invested a total of $1,600 in two mutual funds. One fund earned a 9% profit while the other earned a 4% profit. If the investor's total profit was $84, how much was invested in each mutual fund?
The amount invested in each mutual fund is $400 and $1200 respectively
What is Simultaneous equation?Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. For example, below are some simultaneous equations: 2x + 4y = 10 and 8x − 4y = 2
Let represent the amount the first fund get by x and the amount the second fund get by y.
Therefore x+y = 1600 equation 1
and 9/100 × x + 4/100 × y = 84
9x/100 + 4x/100 = 84
multiply through by 100
9x + 4x = 8400 equation 2
using elimination method
9x+ 9y = 14400 equation 3
9x + 4y = 8400 equation 4
subtract equation 4 from 3
5y = 6000
divide both sides by 5
y = 6000/5
y = $1200
substitute 1200 for y in equation 1
1200+x = 1600
x = 1600-1200
x = 400
Therefore the first fund will get $400 and the second fund will get $1200
