Answer:
Option C. 
Step-by-step explanation:
we know that
If a system of two linear equations has an infinite number of solutions, then both equations must be identical
The given equation is

<u><em>Verify each case</em></u>
Option A. we have

apply distributive property

Compare with the given equation

Option B. we have

remove the parenthesis

Compare with the given equation

Option C. we have

apply distributive property

Compare with the given equation

therefore
This equation with the given equation form a system that has an infinite number of solutions
Option D. we have

Compare with the given equation

132min=2h 12min
15:35 + 2h 12min=17:47
Your answer would be B.

What changes may occur if the given dollar will be rounded off to its nearest value.
<span>There will only be 2 chances, the dollar will become smaller or bigger. Why? </span>
Because in mathematical rules of rounding off numbers:
number below 5 will be round down and 5 and up will be rounded up.
For example:
You have a bill of $6.79 since the number next to the decimal point in the right is 7, it will be rounded up to $7.
<span>But if your bill is $6.25, it will be rounded down to $6.00
