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

9x + 7y = -12 find the value of y when x equals 1

Answers

Answer:

y = -3

Step-by-step explanation:

9x + 7y = -12

Let x = 1

9 (1) + 7y = -12

9  + 7y = -12

Subtract 9 from each side

9 -9 + 7y = -12-9

7y = -21

Divide each side by 7

7y/7 = -21/7

y = -3

Answer:

y = -3

Step-by-step explanation:

9x + 7y = -12

9(1) + 7y = -12

9 + 7y = -12

7y = -12 - 9

7y = -21 (divide both sides by 7)

y = -3

Which equation could be used to solve the problem? Tony is on a train that travels 99 mi in 1 h.

At that rate, how many miles (d) will the train travel in 9 h ?

A.
d = 99 + 9

B.
d = 99 ÷ 9

C.
d = 9 ÷ 99

D.
d = 99 • 9

Answers

it is D you will have to Multiply because its say How many mile so thats how i find out
The equation is D. If the train goes 99 miles per 1 hour thats 99 multiplied by 1. But if you substitue the 9 in for the 1 then its 99 times 9:)
