For this question, you will now need to solve for both a and b, you can break down the expression that they want you to find:

(a^2-b^2)/(a-b)
= (a+b)(a-b)/(a-b) (Difference of squares)
= a+b (The (a-b) is common at the top and bottom so they will cancel

Now a+b =

Find the values of x and y
pantera1 [17]

Answer:

x = 15°

y = 59°

Step-by-step explanation:

Angles at a right angle add up to 90°

41 + y = 90

y = 90 - 41

y = 59°

Angles in a triangle add up to 180°

41 + (2x - 9) + 7x + 13 = 180

41 + 13 - 9 + 2x + 7x = 180

45 + 9x = 180

9x = 180 - 45

9x = 135

x = 135/9

x = 15°

Observe the graph below. The scale factor used to dilate ABC was...
Lera25 [3.4K]

Answer:

3

Step-by-step explanation:

AB = 1 unit

A'B' = 3 units

The scale of dilation = A'B'/AB

Therefore:

scale of dilation = 3 units / 1 unit = 3

This means that ABC was dilated or enlarged in size by multiplying every of its segment by 3. In essence, A'B'C' is 3 times the size of ABC.
