There is only one answer
The slope intercept it (0,4)
Answer:
A= 65 in. ^2
Step-by-step explanation:
first make them into different shapes
I made 3 different rectangles
#1 4 by 6
#2 4 by 8
#3 3 by 3
for a area of a rectangles you do base times the height
#1 6*4 = 24
#2 4*8 = 32
#3 3*3 = 9
now you add them up
24+32+9
= 65 in. ^2
A(x) = 3x - 12
b(x) = x - 9
a(b(x)) = a(x - 9) = 3(x - 9) - 12 = 3x - 27 - 12 = 3x - 39
a(b(x)) = 3x - 39
The are for the square is 68 inches
