Question

WILL GIVE BRAINLIEST! Four expressions are shown below: A. 4(8x + 2) B. 4(7x + 3) C. 32x + 8 D. 28x + 12 Which two expressions are equivalent to 4(7x + 2 + x)? (5 points) A and B B and C A and D A and C

Answer 1

Answer:

A and C.

Step-by-step explanation:

4(7x + 2 + x) simplifies to

4(8x + 2)

= 32x + 8.

So A is one expression.

So is  C.

B = 28x + 12 and D = 28x + 12  so are not equivalent.

Answer 2

Answer: A. 4(8x + 2), and C. 32x + 8

Step-by-step explanation:

Put the equations together and if they have infinitely many solutions they'll both be equal to each other.

CORRECT 4(7x + 2 + x)=4(8x + 2)

7x+2+x=8x+2

8x+2=8x+2 (Infinitely Many Solutions)

CORRECT 4(7x + 2 + x)=32x+8

4(8x+2)=32x+8

32x+8=32x+8

32x+8=32x+8 (Infinitely Many Solutions)

INCORRECT 4(7x + 2 + x)=4(7x + 3)

8x+2=7x+3

8x=7x+1

8x−7x=1

x=1

INCORRECT 4(7x + 2 + x)=28x + 12

4(8x+2)=28x+12

32x+8=28x+12

32x=28x+4

32x−28x=4

4x=4

x=1

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)
