Use the X-intercept method to find all real solutions of the equation. 23-7x + 7x + 15 – 0 a. X=-1, 3, or -- 5 2--1, 3, or 5 b. 4-1. – 3. or - 5 d. 1 = 1, -3, or 5

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
