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! :-)

89 km would be about 55.3 miles! that's the best answer, but if they want you to round then I'd say choose 55 miles
The answer is D, which is 32. Hope this helps.
