I will help if you post a picture or something
you're given the pythagorean theorem, which is a^2 + b^2 = c^2.
what you're trying to find is ?, which is the number under the radical.
let's pretend one leg is a and the other is b.
a = 9
b = 10
so let's plug it into the equation. we get 9^2 + 10^2 = c^2
so that equals 81 + 100 = c^2
181 = c^2
so c will equal the square root of 181. therefore, ? = 181.
hope i helped! good luck.
Answer:
x = 20
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Answer:
-63
Step-by-step explanation:
Write the problem as a mathematical expression.

Simplify 4−4−8 to substitute in f(x)=−x^2+1
Subtract 4 from 4

Subtract 8 from 0

Replace the variable x with −
8 in the expression

Simplify


Answer = -63
