It’s answer C. You multiply 8 & 13, which will give you 104. Then, multiply 8 & 2y, which will also give you 16y.
The answer is x=-7
8x-7x-2=-9
8x-7x=-9+2
-7
Lateral surface area = (23×12.04)+(23×8)+(23×9)
= 276.92 + 184 + 207
=667.92
= 668m²
Total surface area = 668 + 1/2(2×8×9)
= 668 + 72
= 740m²
Answer:
x = -2
y = 1
Step-by-step explanation:
-3x - 4y = 2
x = -2
y = 1
3x + 3y = -3
x = -2
y = 1
