Answer:
x = 64 m
Step-by-step explanation:
The scale is proportional to the actual:
(6 m)/(3/4 cm) = x/(8 cm)
Multiplying by 8 cm, we get ...
x = (8 cm)·(6 m)/(3/4 cm)
x = 64 m . . . . the width of the actual wall
Find f(-2) f(x)=9x^2-5x+2
f(-2) means replace x in the equation with -2:
f(-2)=9(-2)^2-5(-2)+2
= 9(4) +10 + 2
= 36 +10 + 2
= 48
f(-2) = 48
