Guy wants to swim 500 meters. After 75 meters, he takes a break. What percent of his goal has he already met?
iren2701 [21]
To determine this, we need to set up proportions.
x/100 = 75/500.
A quick way to find x, the percentage we're looking for, is to cross multiply our fractions.
100 x 75 and 500 with x.
75 x100 = 7500, and 500 times x is 500x.
7500=500x
Divide by 500 on each side.
15 = x
Your answer is C.)15%.
I hope this helps!

Select all the factors roots of x^3 +2x^2-16x-32
Ivanshal [37]

Factor by grouping. Group up the terms into pairs, factor each pair, then factor out the overall GCF.

x^3 + 2x^2 - 16x - 32

(x^3 + 2x^2) + (-16x-32) ... pair up terms

x^2(x + 2) + (-16x - 32) ... factor x^2 from the first group

x^2(x + 2) - 16(x + 2) ... factor -16 from the second group

(x^2 - 16)(x + 2) .... factor out (x+2)

(x - 4)(x + 4)(x + 2) .... Use the difference of squares to factor x^2-16

---------------------------

The original expression completely factors to (x - 4)(x + 4)(x + 2)

The three factors are x - 4  and  x + 4   and   x + 2
