Step-by-step explanation:
area = 15 x 8
Since the end of the slide is 1 foot above the ground, the vertical rise of the
<span>slide is 8 - 1 = 7 feet, and since the slide rises at a 45 degree angle it will </span>
<span>have a horizontal run of 7 feet as well. Thus by Pythagoras the length of the </span>
<span>slide is sqrt(7^2 + 7^2) = sqrt(98) = 9.90 feet, which is about 10 feet.</span>
Answer: idk if there’s any specific choice, but it should be the case.
Step-by-step explanation:
if n^2 is divisible by 3, n must also be divisible by three, since its squaring n by itself. probably a bad explanation. 3^2 is 9, 9^2 is 81, 12^144. all of them are divisible by three. Basically think of it as: 9^2 is (3x3)^2. 12 is (3x4)^2. So if n^2 is divisible by 3, n should also be divisible by 3. Sorry for the bad explanation. also I hope it’s right, sorry if it’s wrong.
