Answer:
4(2x+1)(x−1)
Step-by-step explanation:
8x2−4x−4
8x2−4x−4
=4(2x+1)(x−1)
Two possible numbers that might have a GCF common factor of 5 are 10 and 15, as well as 25. 5 is also the greatest common factor of itself.
So your numbers are : 5, 10, 15, and 25.
13/15 = 87%
This is because 13 divided by 15 is 87, so 13 is 87% of 15:)
Answer:
x = 5 pens
y = 7 pencils
Step-by-step explanation:
let
x = the number of pens
y = the number of pencils
Anthony spent $2.80 to buy a total of 12 pens and pencils
0.35x + 0.15y = 2.80
x + y = 12
by solving the system of equations
0.35x + 0.15y = 2.80
x + y = 12
we find
x = 5 pens
y = 7 pencils
s=3f-24
add 24 to each side
s+24 =3f
divide by 3
(s+24)/3 = f
Answer: f=(s+24)/3 or 1/3 s +8
