Answer:
A = 136 cm²
Step-by-step explanation:
There are three pairs of rectangular faces
A = 2(ab) + 2(bc) + 2(ca)
A = 2(ab + bc + ca)
A = 2(3(4) + 4(8) + 8(3))
Medbay
y = 2x + b passes through point (-3, 0), so:
0 = 2(-3) + b
0 = -6 + b
b = 6
Therefore the equation: <u>y = 2x + 6</u>
The range is from 4 to -2 is 6
