Answer:

The answer is D.

Step-by-step explanation:

First you have to get rid of brackets by expanding :

$3 {q}^{2} + {r}^{3} + 5r - 8q + 2( {q}^{2} + r)$

$= 3 {q}^{2} + {r}^{3} + 5r - 8q + 2 {q}^{2} + 2r$

Next you have to simplify by collecting like terms :

${r}^{3} + 3 {q}^{2} + 2 {q}^{2} + 5r + 2r - 8q$

$= {r}^{3} + 5 {q}^{2} - 8q + 7r$

I NEED HELP PLEASE. LOOK AT PICTURE

Answer:

Part 1) $\frac{a^4}{4b^2}$

Part 2) $-\frac{v^9}{w^6}$

Step-by-step explanation:

we know that

When divide exponents (or powers) with the same base, subtract the exponents

Part 1) we have

$\frac{3a^{2}b^{-4}}{12a^{-2}b^{-2}}=(\frac{3}{12})(a^{2+2})(b^{-4+2} )=\frac{1}{4}a^{4}b^{-2}=\frac{a^4}{4b^2}$

Part 2) we have

$\frac{v^3w^{-3}}{-v^{-6} w^3} =-v^{3+6}w^{-3-3}=-v^9w^{-6}=-\frac{v^9}{w^6}$

Answer:

The answer could be A) or D) because the zero acts as a place holder. Its a little easier to derive it if you have a bigger decimal
