A. 564 in2
B. 664 in2
C. 1,120 in2
D. 1,080 in2

maybe C?

Step-by-step explanation:

tell me if im wrong

1,120 in2

Step-by-step explanation:

surface area= l×w×h

=10(14)(8)

=140(8)

=1,120

Hi there!

The way that an infinite number of solutions is achieved is when the two equations, when solved together, get an answer which is just a number equal to the same number. To do this, first substitute 6x-b in for y in the second equation.

Now, we see that b needs to be equal to -3 when multiplied by -1/2. When both sides are divided by -1/2, b becomes equal to 6. Thus, b must be 6.

Check work:

Thus, as they are equal to each other, the answer is correct. b = 6.

Hope this helps!
