Answer: 375
Step-by-step explanation: If the problem was pythagorean theorem. Then I hope this explantion will help.
5 squared and 20 squared. 5 squared would get you 25 and 20 squared should get you 400. Then you should take 400-25=375. Your answer therefore is 375
I hope this helped!
3-(2x-5)=-4(x+2)
We simplify the equation to the form, which is simple to understand
3-(2x-5)=-4(x+2)
Remove unnecessary parentheses
3-2x+5=-4*(x+2)
Reorder the terms in parentheses
3-2x+5=+(-4x-8)
Remove unnecessary parentheses
+3-2x+5=-4x-8
We move all terms containing x to the left and all other terms to the right.
-2x+4x=-8-3-5
We simplify left and right side of the equation.
+2x=-16
We divide both sides of the equation by 2 to get x.
x=-8
