Need in math will give 1. –18 + 15x = 3(4x – 6) + 3x 2. –10 + 5x = 5(x – 3) + 5

1. -18 +15x = 3(4x-6) + 3x

-18 + 15x = 12x - 18 + 3x

-18 + 3x = -18 + 3x

3x = 3x

x = All Real Numbers (because we don't know what x is since the equation is 3x = 3x, we can assume that it is all "real" numbers)

2. -10 + 5x = 5(x - 3) + 5

-10 + 5x = 5x - 15 + 5

-10 = -10

Answer Undefined (because the x coefficients canceled out, we don't know what x even is, so we can claim it as undefined.)

answer: 32.68

step-by-step explanation:

x=2

a² + b²= c²

24² + 7² = c²

c= 25
