"The absolute value of an integer is its distance from zero on a number line. For example, the absolute value of -8 is +8, because -8 is 8 units from zero on the number line. Note that the absolute value of any positive or negative integer is positive." http://www.mathhelp.com/how_to/integers_and_the_number_line/opposites_and_absolute_value/

Opposite:
Just change the sign.
If it's a positive number, make it negative.
If it's a negative number, make it positive.

Absolute value:
Even easier.
Just throw away the sign, and you have it.

Use distributing property : (-11) x (-15) + (-11) x (-25) plzz answer fast
Semmy [17]
The answer is 440.
What I do is just take the -11 and -15 out of the parentheses so it is -11*-15 and the answer is 165. Then, you take -11 and -25 out of the parentheses and find the answer.
Add them together.
Hope that helped :)

x^2 + b/ax + __ = c/a + __

Take the coefficient of x

b/a

Divide by 2

b/2a

Square the expression
