B. QUI
C. QV
D. QIII

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

3x^3-2x^2+4x-3= -3

x^2+3x+3= 3

-3÷3= -1
