Answer:
B. (x−2)
Step-by-step explanation:
Factor out x^2
x^2(x+2)-4x-8
Factor out 4
x^2(x+2)-4(x+2)
Now combine
(x^2-4)(x+2)
Factor x^2-4 (notice that it is a difference of squares)
(x+2)(x-2)(x+2) -x+2 is twice so we can square it
(x+2)^2(x-2)
Answer:
y+4=-36 and the answer is y=-40
Step-by-step explanation:
So the word is means equals, meaning we can change it to say
"y more than 4 = -36
and more than means addition so we can put a plus sign there and we get
y+4=-36
then to solve this equation we need to get y by itself on one side and to do that we can move the 4 to the other side by subtracting it on both sides to cancel out the addition and we get y=-40

Answer:
Below.
Step-by-step explanation:
We can write an odd integer as 2x + 1 so consecutive odd digits would be 2x + 1 and 2x + 3, so the equation is:
2x + 1 + 2x + 3 = 156
4x + 4 = 156 can be used to solve for x and find the integers.
4x = 152
Dividing through by 4:
x = 152/4 = 38
So the 2 integers are 2(38) + 1 and 2(38) + 3
= 77 and 79.
Answer:
(x − 2) = 3
Remove the bracket
x - 2 = 3
Group the constants at one side of the equation
x = 2 + 3
x = 5
Therefore x = 5.00 to 3 significant figures.
Hope this helps
