The polynomial

may have solutions which are the divisors of -20, therefore -20 has the following divisors:

.
If x=1, then

,
if x=-1, then

,
if x=2, then

, then x=2 is a solution and you have the first factor (x-2).
If x=-2, then

, then x=-2 is a solution, so you have the second factor (x+2).
Since x-2 and x+2 are two factors of

, then the polynomial

is a divisor of

and dividing the polynomial

by

you obtain

.
Two fractions that are equal to 2/5 are 4/10 and 6/15. In order to find fractions that are equal to it, just multiply both the numerator and the denominator by any number. I multiplied them by 2 and 3, to keep things simple.
2 x 2 = 4
2 x 5 = 10
4/10
2 x 3 = 6
5 x 3 = 15
6/15
Hope this helps!

ANSWER: 384
Given:
An unpainted roof. Assuming the dimensions of the roof are 10 meters by 5 meters by 0.2 meters. To solve for the total surface area of the roof to be painted:
SA = 2 (wl + lh + wh)
SA = 2 ( 10*5 + 10*0.2 + 5*0.2)
SA = 106 square meters
Answer:
X=84
Y=64
Step-by-step explanation:
84+64+32= 180
Triangles always equal 180
