First distribute 4 into the corresponding parenthesis.
4x+12
Then distribute 2 into the other corresponding parentheses.
4x+18
So together you get 4x+12=4x+18
No we want to get all our variables on one side and our numbers on the other side.
We can do this by combining like terms/
First subtract 12 from both sides
4x=4x+30
Then subtract 4x from both sides
0=30
The equation is false

Paul [167]

Answer: can u check out the image cuz the answer is in the photo and hope this helps can u give me brainliest

Step-by-step explanation:

24=3(n-5)

Distribute.

24=3(n) + 3(-5)

24 = 3n -15

Add 15 to both sides.

39 = 3n

Divide both sides by 3.

n = 13.

I hope this helps!.

For synthetic division:
1) Write the coefficients of the polynomial under the division symbol, in order. Make sure you include coefficients that are 0, so they may not be written out in the polynomial! 
The coefficients are 7, 1, 0 (the coefficient of x), and -4 in that order

2) The divisor is in the form of x - a. The number "a" goes outside the bracket.
a = 5

Since 7, 1, 0, -4 are under the bracket and 5 is outside the bracket, the answer is C.

------

Answer: C
