Answer:
The other leg is 24 ft.
Step-by-step explanation:
49+x2=625. x2=576. x=±24→ Eliminate the -24 answer choice; a side length cannot be negative.
5-2x=4-2x+4+x=8-x
x=5-8=-3
C
40x-24
3b(6c-3a+c)
For the first one use distributive property and multiply each term by 8.
For the second one find a common factor which is 3b and divide all terms by that number.
