Answer:
x = 0 x= -9
Step-by-step explanation:
x^2 + 18x = 9x
Subtract 9x from each side
x^2 + 18x-9x = 9x-9x
x^2 +9x = 0
Factor x from the left hand side
x(x+9) =0
Using the zero product property
x=0 x+9 = 0
x =0 x+9-9 = 0-9
x = 0 x= -9
Answer:
6
Step-by-step explanation:
The first number: a

Step-by-step explanation:
Answer:
a.-11 . b.11
Step-by-step explanation:
6x-17= -11 . 4x+7= 11
angle CEB and AED are corresponding angles, so they are both are equal
since we already know that CEB is equal to 160, that means that AED is also equal to 160
all you have to do to find the value of x is subtract the 115 from 160, and so you get 45
so, x=45
hope this helps!! :)
