I too also need this answer.
Answer:
B. 30
Step-by-step explanation:
Boys to girls
2 : 3
Units of girls = 3
3 units = 18
1 unit = 18 ÷ 3 = 6
Total number of units = 2 + 3 = 5
5 units = 6 x 5 = 30
if 1 inch is added, you would add 2 inches to to each side of rectangle.
You would have: W+2, and, L+2,
Now let W+2 = x and, L+2 = y
Total area = x*y=M
If 1 inch is added again, like above you add 2 inches to both sides, you would then have:
(x+2)(y+2)=M+52;
xy+2x+2y+4=M+52;
xy=M
2x+2y=48
x+y=48/2=24
Now solve :
W+2+ L+2=24
W+L=20
The perimeter is 2(W+L)=20*2 = 40 inches.
Answer:
15
Step-by-step explanation:
The product of the prime factors of 3375 are
3375 = 3³ × 5³, then
![\sqrt[3]{3375}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B3375%7D)
= ![\sqrt[3]{3^3(5^3)}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B3%5E3%285%5E3%29%7D)
= ![\sqrt[3]{3^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B3%5E3%7D)
× ![\sqrt[3]{5^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5%5E3%7D)
= 3 × 5
= 15
