Replace a with the length of the given leg and c with the length of the hypotenuse and solve for b:
7^2 + b^2 = 25^2
Simplify"
49 + b^2 = 625
Subtract 49 from each side:
b^2 = 625 - 49
b^2 = 576
Take the square root of both sides to solve for b:
b = √576
b = 24
Answer:
5*x-3=12
the number is 3 because 5*3=15 and 15-3=12
If you solve for x by getting it on one side, it becomes 7/5.
Step-by-step explanation:
