Answer:

8000

Step-by-step explanation:

Let the required number be x.

$\therefore \: \frac{3}{8} \% \: of \: x = 30 \\ \\ \therefore \: \frac{3}{800} \times x = 30 \\ \\ \therefore \: x = 30 \times \frac{800}{3} \\ \\ \therefore \: x = 10 \times 800 \\ \\ \therefore \: x = 8000 \\$

Find the sum of these polynomials

Nuetrik [128]

Hi there! The answer is B.

$( {x}^{2} - x + 7) + (9 {x}^{2} + 6)$
First we work out the parenthesis, which is easy because we can just remove them.

${x}^{2} - x + 7 + 9 {x}^{2} + 6$
Now rearrange our expression (in order to collect terms later).

${x}^{2} + 9 {x}^{2} - x + 7 + 6$
Next up is collecting the terms.

$10 {x}^{2} - x + 13$
The answer is B.

~ Hope this helps you!
