Identify the property used in step 3.
step 1 2 + 2x + 10 + 11x - 10 = 2 + 2x + 10 + (11x - 10)
step 2 = 2 + 2x + 10 + (-10 + 11x)
step 3 = 2 + 2x + [10 + (-10)] + 11x
step 4 = 2 + 2x + 0 + 11x
step 5 = 2 + 2x + 11x
step 6 = 2 + (2 + 11)x
step 7 = 2 + 13x
step 8 = 13x + 2

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

3+x
