Tbh I would say ounces or grams. I wouldn't make a final decision on my answer though.

Answer:
the error is that you have passed the negative sign alongside with the 0.8 but you have corrected by putting the -0.8 in the parentheses. if you used a computer check your answer something that could have messed up was the negative sign on the right side of the r in the part where It says r=12.6+(-0.8)
Answer:
2x² + 3x
Step-by-step explanation:
Using distributive property, you can multiply the variable outside the parenthesis to both terms inside the parenthesis:
x(2x + 3) = 2x(x) + 3(x) or 2x² + 3x
When multiplying with the same base, you will add the exponents.
H(t) = 0 for t = 7 and for t = -2.
It is reasonable for the time to be positive, 7 seconds.
(The offered answers all appear to be negative, so none are reasonable.)
