Please Help 7th grade math

The signs of the numbers in the problem matter because if a number is negative in the equation than you're answer could be negative. ex. -3/9= -3 but if the negative sign wasn't there than the answer would be wrong bc the answer would be positive.

hope thats what you need hope it helps.

Am I right ? Because I need help with this please thanks.

to find the hypotenuse (or the ramp in question 4) you can use the equation

$a^{2} +b^{2} =c^{2}$

with a and b being the 3 feet and 9 feet and c being the unknown (ramp).

So if you plug 3 and 9 into the equation, it looks like this.

$3^{2} +9^{2} =c^{2}$

then square them.

$9+81=c^{2}$

simplify.

$90=c^{2}$

take the square root of both sides.

$\sqrt{90} = c$

$\sqrt{90}$ is approx. 9.5 so the answer would be H.
