Answer:
Plz don't delete...cuz im tryna help '-'
Step-by-step explanation:
25r²-100=0
25r^2 = 100
cuz the (-) will turn (+) when taken to the other side of the (=) sign
25r^2 = 100
<em>divide both sides by 25</em>
<em>divide both sides by 25 then we get </em>
r^2 = 4
r^2 = 2^2
<em>now take the sqare roo</em><em>t</em><em> of both sides</em>
r = 2
The answer is B I hope this helps you

Ok I also need help with this can you help???? I will try helping you with that homework
Start by calling the shortest side
. We then know that the longer leg (call it
) is 7 feet longer i.e.
. We also know that the hypotenuse,
is 1 foot more than twice the short leg i.e.
. We now have 3 unknowns but only 2 equations to solve them. Luckily we know this is a right triangle so we can use the Pythagorean Theorem as our third equation:
Substituting known values:
This is now an equation in one variable and can be solved algebraically for
. Back-substitution can then be used for the other sides.
