Answer:
x = - 14, x = - 4
Step-by-step explanation:
Given
(x + 9)² = 25 ( take the square root of both sides )
x + 9 = ± = ± 5
Subtract 9 from both sides
x = - 9 ± 5, that is
x = - 9 - 5 = - 14 or x = - 9 + 5 = - 4
Answer:
To solve for inequalities you need to get x by itself
To do this we need to perform the opposite operation that is happening to the variable
3x<18 (x is being multiplied by 3, so we want to divide by 3 to get the x by itself)
x<6 (3/3=1. 18/3=6) Keep the sign the same as before
x<6
Hope this helps ;)
