Answer:
c=28
Step-by-step explanation:
In a convex polygon, all the exterior angles are congruent to each other.
I'll be choosing the two angle degrees of 4c-28 and 3c and set them equal to each other.
4c-28=3c
Therefore, c=28
The answer is B estimated number is 20
Answer:
D) 8x²-172x+120
Step-by-step explanation:
Length=2(-2x+20)+6
Width=-2x+20
(-4x+40+6)(-2x+20)
(-4x+46)(-2x+20)
8x²-80x-92x+920
8x²-172x+920
Add 5 on both sides
Make the denominators the same

Multiply 13 on both sides
