The second answer since f goes inside g which gives u 5x^2
1/3(x) = 5/6(x) - 15
2/6(x) = 5/6(x) - 15
15 = 1/2(x)
x=30
![8 < \sqrt[3]{a} < 9](https://tex.z-dn.net/?f=8%20%3C%20%5Csqrt%5B3%5D%7Ba%7D%20%3C%209)

So, a can be any number between (512, 729).
∴ answer is (A) 679
First you need to find out how many inches are in a yard. After that, times that by 2 1/4 or use the improper fraction form 9/4 which I am going to use.
We know there is 36 in = 1yd
36 x 9/4 = 324 / 4
324 / 4 = 81 inches
Answer:
this is the answer I hope it helps
