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! :-)

Answer:
6/25
Step-by-step explanation:
First, we’re going to use this formula:
2nd number - 1st number
————————————— x 100%
1st number
If we plug in the numbers to this equation:
23-20
———- x 100%
20
And subtract 23 to 20, the answer to this equation is:
3
—- x 100% = 15%
20
In this case, the percent of increase is 15%.
