The answer B. Hope this helps!
Answer: the answer is 100
Step-by-step explanation:
Answer: 1.5x
Step-by-step explanation:
If the figure dilates by 1.5 times it will increasingly do the same with the perimeter. It keeps the same ratio of 1.5x.
Ex: If a side of the figure was originally 10 and the dilation factor is 1.5 the side now with be 15. This goes for all sides.

The trick here is realizing that both angles equal each other. There's a rule for this, but generally you can tell just by looking.
So what we can do is set these two equations equal each other, solve for x, and then plug x into angle B's original equation.
8x - 10 = 3x + 90
5x = 100
x = 20
now we plug that x into angle B
3x + 90
3(20) + 90
60 + 90
150
Angle B = 150°
Answer:
c = 169
Step-by-step explanation:
Given
m² - 26m
To complete the square
add ( half the coefficient of the m- term)² to m² - 26m
m² + 2(- 13)m + (- 13)²
= m² - 26m + 169 ( with c = 169 )
= (m - 13)² ← perfect square
