Answer:
1. terms = 2, 3a, 9a ; like terms = 3a, 9a ; coefficients = 3, 9 ; constants = 2
2. terms = 7, -5x, 1 ; like terms = 7, 1 ; coefficients = -5 ; constants = 7, 1
Green rectangle = length * width * height

Pyramid = 1/3 *base^2 * height
1/3 * 16^2 * 10 = 853.33
Answer:
<h3>55 secs</h3>
Step-by-step explanation:
Given the elevation h (in feet) of the balloon modeled by the function h(x)=−6x+330, we can calculate the time it takes the balloon to reach the ground. The hot air balloon hits the ground at h(x) = 0.
Substitute h(x) = 0 into the modeled expression and find x as shown;
h(x)=−6x+330
0 = −6x+330
6x = 330
Divide both sides by 6
6x/6 = 330/6
x = 55 seconds
Hence the hot air balloon hits the ground after 55 seconds
