Answer:
x = 2 x = -6
Step-by-step explanation:
2 (x+2) ^2-4=28
Add 4 to each side
2 (x+2) ^2-4+4=28+4
2 (x+2) ^2= 32
Divide by 2
2/2 (x+2) ^2=32/2
(x+2)^2 = 16
Take the square root of each side
sqrt((x+2)^2) =±sqrt( 16)
x+2 = ±4
Subtract 2 from each side
x+2-2 = -2±4
x = -2±4
x = -2+4 and x = -2-4
x = 2 x = -6
Answer:
w = 15
Step-by-step explanation:
-9(w + 585) = -360w
-9w -5265 = -360w
351w = 5265
w=15

I do not think it is easy to explain this answer.
Answer:
x = - 6
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable (x). Divide -15 from both sides
(-15x)/-15 = (90)/-15
x = 90/(-15)
Divide.
x = 90/-15
x = -6
*Remember that when you divide a negative number and a positive number, the result will be a negative answer.
-6 is your answer
