Answer: -x^4 - 3x^3 - x^2 + 4x + 6
Explanation
Answer:
a = 6, b = 22.5
Step-by-step explanation:
One triangle is 2.5 times bigger than the other.
9*2.5=22.5 which means b = 22.5

Answer:
x=29°
Step-by-step explanation:
as lines are parallel.
external alternate angles are equal.

7x-4x=1+86
3x=87
x=87/3=29
