Vertical Angles: angles that are opposite of each other congruentStep-by-step explanation:
Step 1: Set up equation
5x + 2 = 3(x + 14)
Step 2: Solve for x
Distribute 3: 5x + 2 = 3x + 42Subtract 3x on both sides: 2x + 2 = 42Subtract 2 on both sides: 2x = 40Divide 2 on both sides: x = 20Step 3: Find m∠KNL
Define: m∠KNL = 3(x + 14)°Substitute: m∠KNL = 3(20 + 14)°Add: m∠KNL = 3(34)°Multiply: m∠KNL = 102°9.

Grandma’s Garden has an area of 95 square feet. The. Length of one side of her garden would be between what two whole numbers? What is the length of this side to the nearest tenth of a foot? Represent this number on a number line as a square root and a decimal.
Answer:
Between 9 and 10
Step-by-step explanation:
Area = 95 square feet
The garden is a square
[tex]a^2 = 95[/tex]
a = [tex]\sqrt{95}[/tex] = 9.75
The two whole numbers for side length is between 9 and 10.
The length of this side to the nearest tenth of a foot is 9.8ft.

ABC is an isosceles triangle.
• AB = AC = 11 cm
E
. E and F are the midpoints of AB
and AC respectively,
• EF is parallel to BC.
55
B
Find the area of the trapezium BEFC.
Answer: 90,75. cos 55°. sin55° ≈ 42,64
through E, draw EK perpendicular to BC (F ∈ BC)
because E is the midpoint of AB => BE = 11/2 = 5.5
ΔBEF is a right triangle at K
=> sin 55° = EK/BE
=> EK = 5,5.sin 55°
ΔABC has E and F is the midpoints of AB and AC
=> EF is the median line of the triangle
=> EF = 1/2.BC
through A, draw AD perpendicular to BC
=> ΔABD is a right triangle at D
=> BC = 11.cos 55°.2 = 22.cos 55°
=> EF = 11.cos 55°
=>the area of the trapezium BEFC is:
[tex]\frac{5,5.sin55(11.cos55+22.cos55)}{2}=90,75.cos55.sin55[/tex]

What is the sum?
(2x + 5) + (x - 1)
Answer:
3x+4
Step-by-step explanation:
Parenthesis are not needed in this equation because it is all addition and subtraction. This means another way to write the equation is:
2x+x+5-1
Combine like terms and the answer you get is:
3x+4
I give Brainliest. Can somebody help me with this pls??
Answer:
Ok so we see that at the end there is a +2 so the first thing we want to do is start our first point at (0,2). After that we can see that our slope is -1/2, since slope equals x/y we know that it is asking us to go 1 to the right, however since it is negative we will be going 2 down. the Y intercept is the point where the line intercepts the Y-axis which is (0,2)
Step-by-step explanation:
Answer:
slope= -1/2
y-intercept = (0,2)
Step-by-step explanation:
The y-intercept is what y equals when x equals zero. On the graph, it is where the graph crosses through the y axis.
To find the y-intercept, plug in 0 for x, so x = 0
y = -1/2 (0) + 2
y=2
and we know x =0
So the point is (0,2)
Question 2: Here are some transformation rules. For each rule, describe whether the
transformation is a rigid transformation (rotation, reflection or translation), a non-rigid
transformation (dilation), or neither.

2. (x, y) (2x, 39)

9514 1404 393
Answer:
rigidnon-rigidnon-rigidrigidStep-by-step explanation:
The transformations of 1 and 4 are translations (1 and 4) and reflection (4), so are rigid transformations.
The transformation of 3 is a dilation by a factor of 3, so is non-rigid.
The transformation of 2 is a horizontal stretch by a factor of 2 and a vertical stretch by a factor of 3. It, too, is a non-rigid transformation, but is not strictly dilation.
It cost Jayden $4.80 to send 96 text messages. How much would it cost to send 155 text messages?
Answer:
$7.75
Step-by-step explanation:
1. Take the cost - $4.80 for the 96 messages, and divide $4.80 by 96 to get the cost per message.
2. 4.80 ÷ 96 = $0.05 per message
3. Take that figure and multiply by 155 messages.
4. 155 × $0.05 per message = $7.75
Hope this helps!

given the function f(x) = 8x2 -14x - 10, find f(-2)
Answer:
-32 I think (plz dont be mad at me if this is wrong)
Step-by-step explanation:
Answer:
f(-2) = 50
Step-by-step explanation:
f(x) = 8x^2 - 14x - 10, find f(-2)
Just like how -2 replaced x in f(x), you will replace x with -2 in the equation
f(-2) = 8(-2)^2 - 14(-2) - 10
f(-2) = 8(4) + 28 - 10
f(-2) = 32 + 18
f(-2) = 50
I have a problem, it says, identify the set of numbers that best describes each situation. The situation is, the amount of money in a bank account. we are working with, real, rational, irrational, integers, and whole numbers. Is it irrational or rational?
Answer:
Rational
Step-by-step explanation:
We first have to define what these numbers mean:
Real numbers are all the numbers on the number line, they are not imaginary numbers that cannot be quantified on the number line.
Rational numbers are numbers that have either terminating decimals or recurring decimal, for example 5.3 (terminating decimal) or 1.333...(recurring decimal). I did not use the traditional definition of "a/b where a and b are integers and b ≠ 0" because it poses some problems. For instance 22/7 fulfills this condition but it is not a rational number! So it is best defined the way I just defined it.
An irrational number is a number that does not have terminating and recurring decimal, like 3.565215805.....
Integers are real numbers that are whole numbers.
Looking at the situation, which is the money in a bank account. The value will be a number that is rational because it is always an exact amount and this implies that it will always be a terminating decimal. Note that 45.00 is also a terminating decimal.
Find x.
9x – 15=7x-1
Answer:
x=7
Step-by-step explanation:
First, add 15 to both sides (whatever you do to one side, do it to the other), this will help cancel out the -15 on the right side of the equation,
so 9x-15+15=7x-1+15, the 15 cancels out and we get 9x=7x+14
Now we want to simplify this further, lets subtract 7x from both sides,
9x-7x=7x-7x+14, 2x=14
Let's divide both sides by 2 because the 2 and x are held together by "multiplication" so we will break that bond with division and that will leave us with x.
2x/2=14/2
x=7
Our goal is to have a variable on one side and a number on the other, so that is why we are doing this. Also, notice that to solve this equation we were doing the reverse operation. For example, when we added 15 to both sides, we were performing the opposite of subtraction because we had a -15. Remember that variables are connected to numbers through multiplication, so 9x would be the same thing as 9*x

What is the quotient of 5 7 ÷ 5 14 ?
Answer:
= 57 / 514 (Decimal: 0.110895)Step-by-step explanation:
57 / 514
= 57 / 514
(Decimal: 0.110895)
And if that is not what you are looking for here:
Rewrite the equation as
x /14 = 5/ 7 . x/ 14 = 5/ 7
Multiply both sides of the equation by
14.14 ⋅ x /14 = 14 ⋅ 5 /7
Simplify both sides of the equation.
Tap for fewer steps...
Cancel the common factor of 14 .
Cancel the common factor.
14 ⋅ x /14 = 14 ⋅ 5 /7
Rewrite the expression.
x = 14 ⋅ 5 /7
Simplify 14 ⋅ 5/ 7 .
Cancel the common factor of 7 .
Factor 7 out of 14 .
x = 7 ( 2 ) ⋅ 5/ 7
Cancel the common factor.
x = 7 ⋅ 2 ⋅ 5/ 7
Rewrite the expression.
x = 2 ⋅ 5
Multiply 2 by 5 .
x = 10

A shape is shown on the centimetre grid below.
Work out the area of the shape after it has been enlarged by scale factor 2.
State the units of your answer.
Answer:
The area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²
Step-by-step explanation:
The Area is basically a measure of how much space in square units there is inside an object.
As the shape is shown on the centimeter grid.
The shape clearly occupies the space of 5-centimeter squares.We also know that If the scale factor > 1, the image is enlarged.
As we know to determine the area of the shape after it has been enlarged by scale factor 2, all we need to do is to multiply the area of the original shape by 2.
The area of original shape = 5 cm²
The area of the shape after the dilation by a scale factor 2 = 5 × 2 = 10 cm²
Thus, the area of the shape after it has been enlarged by
scale factor 2 will be: 10 cm²
