Answer 4

\[\left(3*s^2 + 11*s-12\right) + \left(16*s^2 - 7*s+16\right) + (s-8)=19 s^2+5 s-4 \]

Answer 5

suare root of 16m^15 I came up with the answer 4m^7 square root of m... is that correct robtobey?

Answer 6

btw thanks for the answer for the perimeter

Answer 7

\[\sqrt{16m^{15}}=4 \sqrt{m^{15}}\text{ or}\text{ }4 m^{15/2} \]

Answer 8

I got 4m ^7

Answer 9

\[\sqrt{16m^{15}}=\sqrt{16}\sqrt{m^{15}}=4\sqrt{m^{15}} \]

Answer 10

Subtract to find the exact answer 30 2/9 - 4 7/ 15

Answer 11

okay thanks!.. That s my last one .. Promise :)

Answer 12

\[\left\{30+\frac{2}{9}\right\}-\left(4+\frac{7}{15}\right)=25\frac{34}{45} \]
