Answer:
-q^2 -q + 72
Step-by-step explanation:
(9+ q)(8-q)
=9(8-q)+ q(8-q)
=72 - 9q +8q -q^2
= -q^2 -q + 72
Step-by-step explanation:
measure of exterior angle = sum of 2 non adjacent angles
4X = 90 + X
3X = go
X=30
exterior angle = 30x 4 =120
The answer is 5+b, so when b= 14.99, then 5+14.99=$19.99
