Answer:
66
Step-by-step explanation:
The bases are both the same so it's 3*3 for both of them.
The sides are also the same so it's 3*4 for all four of them.
3*3+3*3+3*4+3*4+3*4+3*4
9+9+12+12+12+12
18+48

Answer:
x= 1
y = -4
Step-by-step explanation:
8x + 9y = -28
-4x = y
8x + 9(-4x) = -28
8x - 36x = -28
-28x = - 28
x = 1
y = -4(1) = -4
If we take for example 20x1.5=30 the scale factor would create an enlargement
