Step-by-step explanation:

h(x) is positive when h(x) is greater than 0.

When h(x) = 0, 2x + 10 = 0, x = -5

Since this is a straight line graph and the gradient is positive, the interval is (-5,∞).

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math

hi there!
