Answer:
81 inches^3
Step-by-step explanation:
The empty space at the top is
3 inches wide by 9 inches long by (12-9) inches tall
3*9*3 = 81 inches^3
You are given the full length and the lengths of all the sections other than CD.
Subtract the given sections from the entire length to get CD.
12 1/2 - 6 1/2 = 6
CD = 6
If the cheerleader sets 18 cannons there has been 3 touchdowns 6x3=18
Because the zeros are -3 and 2, the factors are (x+3)(x-2)
expand it: x^2+3x-2x-6= x^2+x-6
Exponential growth because a decay would be a fraction in the parenthesis
