Answer:

Step-by-step explanation:

Not 3-3 (which is subtraction), but 3^3 (which involves exponentiation.

3^3 = 27

Also: 2^3 = 8; 5^3 = 125

You will see lots of exponentiation in math; please practice and ask questions about it if you have any doubts.

How do you solve 5(3x+7) =3 (5x+7) ?

Naya [18.7K]

5(3x+7)=3(5x+7)

15x+35=15x+21

cancel out the 15x. If you bring over one of the 15x it's going to naturally cancel each other out.

35=21

35 does not equal 21

it would be the equal sign with the slash coming through it

Answer:

x=7

Step-by-step explanation:

Solve.

7x-5x-3=x+4

Calculate like terms.

7x-5x=2x

Rearrange.

2x-3=x+4

Apply inverse addition.

2x-3+3=x+4+3

2x=x+7

Isolate 2x by subtraction.

2x-x=x-x+7

x=7

Answer:

C. (x + 8) (x + 7)

Step-by-step explanation:

To factor this trinomial, you must split the middle term (15x) into two terms that can be added to get 15x, and multiplied to get 56:

$x^2 + 15x + 56$

$x^2 + 7x + 8x + 56$

Group:

$(x^2 + 7x) (8x + 56)$

Take out the GCF (Greatest Common Factor):

x(x + 7) 8(x + 7)

(x + 8) (x + 7)
