For what values of x is x squared minus 36 equal 5x

9 and -4

Step-by-step explanation:

change the word form to math form so now

x² - 36 = 5x     This look like a factoring problem, so we put it equal to 0

x² - 5x - 36 = 0     Now factor

(x - 9) (x + 4)     We have to find 2 numbers that give -36 when we multiply and -5x when we add

x - 9 = 0

x = 9

x + 4 = 0

x = -4

you can check by plugin the x value to actual equation.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
