Answer: 
Step-by-step explanation:
The Greatest Common Factor (GCF) of a polynomial is defined as the largest monomial that is a factor of all the terms of the polynomial.
In this case, given this polynomial:

You can factor out the Greatest Common Factor applying this procedure:
1. Write the terms of the polynomial in prime factor form:

2. Identify the factors the terms have in common (this will be the Greatest Common Factor). In this case this is:

3. Finally, rewrite the expression in factor form:

Answer:
i think its true
Step-by-step explanation:
Solve for one variable x or y first. So lets solve for x. If you take the first equation x= -12 -5y. You then plug that into the second equation
5(-12-5y) +4y = 24
now you solve for y
-60 - 25y + 4y =24
-21y=84
y=-4
Now you plug in y back into either equation and you get x=8
Answer:
30
Step-by-step explanation:
The pattern is adding going up by 2s.
It goes like this:
+0, +2, +4, +6, +8, +10
0, 2, 6, 12, 20, 30
Hope it helps!

Q: What is the most they could weigh together?
A: 0.74 kg

Q: What is the least they could weigh together?
A: 0.62 kg
=================================================
Work Shown:
x = weight of first ball
y = weight of second ball
each ball has a weight range of 0.31 kg to 0.37 kg, so,

add straight down to get

which simplifies to

the two soccer balls have a weight range of 0.62 to 0.74, inclusive of both endpoints.
--------
Without using algebra, you basically just add the smallest the two weights could be (0.31) to itself to get 0.31+0.31 = 0.62 which represents the smallest the two weights combined can be. The same happens with the largest weight of 0.37 to get 0.37+0.37 = 0.74 as the max weight of both objects together.
