Answer:
x or ??? =497.08
Step-by-step explanation:
15 times percentage of 60 so i think it means it like 15/100 times 60/100
A. (−3, 3)
<span>3x – 4y = 21
</span>3(-3) - 4(3) = 21
-21 = 21 >>>>> not equal
B. (−1, −6)
<span>3(-1) - 4(-6) = 21
</span>21 = 21 >>>>>>>>>>Equal
C. (7, 0)
<span>3(7) - 4(0) = 21
</span>21 = 21>>>>>>>>>>equal
D. (11, 3)
<span>3(11) - 4(3) = 21
</span>21 = 21 >>>>>>>>>equal
Answer:

surface area of cube = surface area of sphere
it means that 6x²=4πr²
x²=
15% of 40 = 6 so I’m guessing it would be 6
