Answer:
Scale is 1/6
Step-by-step explanation:
Since all sides and angles are identical these are congruent triangles
3 ways to solve:
Scale Factor = DE / AB = 12/72 = 1/6
Scale Factor = DF/AC = 7/42 = 1/6
Scale Factor = EF/CB = 11/66 = 1/6
Attached solution and work.
You would multiply it by 4
4(3x^2 +2 )
12x^2 +8
Answer: 4x+20
Step-by-step explanation:
Take the number outside the parentheses, and multiply it by each number inside it, one at a time.
then you simply just combine them.
