Hello from MrBillDoesMath!
Answer:
Choice C, 14
Discussion:
The question is a bit obtuse bust as I understand it if we take x = 14 (Choice C). determined by trial and error, then
sqrt(91x) =
sqrt ( 91 * 14) =
sqrt (1274 ) =
sqrt (49 *26) = => as sqrt(49) = 7 we can simplify the expression
= 7 sqrt(26)
Thank you,
MrB

2500 in standard form is 2.5 × 10³
Dr/dt= 8cmM-¹
dA/dt = ?
but A= πr²
so dA/dr =2πr
but recall
dA/dt = dA/dr • dr/dt
dA/dt = 2πr • 8cmM-¹
dA/dt = 2×π×39 ×8 = 624cm²M-1
your answer would be
24 FEET
