Answer:
x=4
Step-by-step explanation:
5(2x-3)-(x+8)=13
10x-15-x-8=13
9x-23=13
9x=36
x=4
Answer:
Step-by-step explanation:
<em>In a regular pentagon, all the angles and sides are equal. So, to find an angle, divide 540 by 5.</em>
Sum of all angles of regular pentagon = 540
measurement of one angle = 540 ÷ 5
= 108°
∠N = 108°
answer: where is the question?
(g o f)(5) = g(f(5))
f(5) = 3(5) - 9 = 15 - 9 = 6
g(f(5)) = g(6) = (6)² = 36
Answer: 36
