Answer:

I believe it is B. 2x2 + 3x

Step-by-step explanation:

Because x will go into 2x like 2x^2 and if you multiply x * 3 which it would equal 3x. That's the best I can explain it.

Hope my answer has helped you and if not I am sorry.

Hi can you help me pleaseeee?)

<em>So to solve for a variable, you have to isolate that variable onto one side.</em>

Firstly, multiply both sides by j: $h-4=kj$

Next, divide both sides by k and <u>your answer will be: $\frac{h-4}{k}=j$ </u>

Firstly, add g on both sides: $\frac{x}{5}=a+g$

Next, multiply both sides by 5 and <u>your answer will be: $x=5(a+g)$ </u>

Firstly, subtract 5p on both sides: $9c=-4p$

Next, divide both sides by 9 and <u>your answer will be $c=-\frac{4}{9}p$ </u>
