Answer:
-10+6=-4
Step-by-step explanation:
Here's why we use distributive property, so a(b+c) = ab+ac, therefore 2(-5+3) is -10+6, which is equal to -4.

Step-by-step explanation:
start by setting the entire equation equal to 8, since h(t) is the height and 8m is the height we are looking at right now.
subtract 8 from both sides to get:
use the Quadratic equation to find the time, the negative answer does not count.
when you do the quadratic equation you get
In decimal form that's about 2.38 and 0.42 You'd probably go with the 2.38 seconds because the ball starts at 0 seconds, so the lower number is probably to close to the start point.
