Explanation:

Squaring 3 leads to 9. The same applies to -3 as well because . The two negatives cancel out.  This is why the solutions to are -3 and 3. That rules out choice B.

Choices C and D can be ruled out because . We end up with a negative result which contradicts the positive value on the right hand side of the original equation. Sure x = 3 works, but x = -3 does not.

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

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
