Question: After watching some fish 40 feet below the surface of the water, a scuba diver went up 15 feet to explore a coral reef. Use a number line to help you create an equation that shows the location of the coral reef in relation to the water surface.

Answer:

C. -40+15 = -25

Step-by-step explanation:

The diver went down 40 feet underneath the surface, so that would be -40. When the diver went up 15 feet, that would be adding -40 to 15. So, the diver would be going closer to the surface after coming up 15 feet. -40+15 = -25

I really hope this helps!!! Have an amazing day :3

Choose the correct simplification of 9x2(4x + 2x2 − 1). 18x4 + 36x3 − 9x2 18x4 − 36x3 + 9x2 36x4 + 18x3 − 9x2 36x4 − 13x3 + 9x2

topjm [15]

Distribute 9x^2 to all terms in parentheses:

$9x^{2} \times 4x = 36x^{3}$
$9x^{2} \times 2x^{2} = 18x^{4}$
$9x^{2} \times -1 = -9x^{2}$

$18x^4 + 36x^3 - 9x^2$

The answer is <span>18x^4 + 36x^3 − 9x^2.</span>
