What are factors of -40?
(-20)(2)
(-10)(4)   (sum of these factors is 6, which is not what we wanted)
(-5)(8) = -40 and the sum of the factors (-5) and (8) is 3.

{-5, 8} is the list of factors of -40 that add up to 3.

Divide the following polynomials and then complete the quotient. Write your answer in order of decreasing powers of x.
NikAS [45]
The easiest way to do this is to put each term in the numerator over the denominator and do the division/reducing for each one.  Like this: \frac{10 x^{6} }{5 x^{2} } + \frac{20 x^{4} }{5 x^{2} } - \frac{15 x^{2} }{5 x^{2} }.  The first term reduces to 2 x^{4}, the second to 4 x^{2}, and the third to 3.  Putting them all together with the signs in between we have 2 x^{4} +4 x^{2} -3

To cover a rectangle region of her yard, Penny needs at least 170.5 square feet of sod. The length of the region is 15.5 feet. W
gulaghasi [49]
We know that the perimeter of a rectangle is 2(width)+2(length). We can multiply the length by 2 to find out how much remaining fencing we have, then divide that number by 2 to find the width.

15.5*2=31
170.5-31=139.5
139.5/2=69.75

A possible width is 69.75 feet.
