5a -5=7+2+2a I really need help​

Answers

Answer 1
Answer: 5a-2a=7+2+5
a(5-2)=14
a=14/5-2
a=14/4
a=3.5
Answer 2
Answer:

Answer:4 2/3

Step-by-step explanation:

5a-5=7+2+2a (combine like terms; 7+2=9)

5a-5=9+2a (subract 2a from both sides; 5a-2a=3a)

3a-5=9 (add 5 to both sides; 9+5=14, -5+5=0)

3a=14 (divide both sides by 3; 14/3= 4 2/3)

Find the greatest common factor 2x^2a+2xa^2

Answers

Answer:

The GCF is

2ax

Step-by-step explanation:

The given expression is:

2 {x}^(2) a + 2x {a}^(2)

We rewrite each term as product of primes to get:

2 {x}^(2) a = 2 * {x}^(2) * a

2x {a}^(2)= 2 * x * {a}^(2)

The greatest common factor is the product of the least powers of the factors common to the prime factorizations.

GCF = 2 * x * a = 2ax
