Number of small boxes:65
Step-by-step explanation:
Let be "l" the number of large boxes and "s" the number of small boxes.
Set up a system of equations:
Use the methof of elimination. Mulitply the first equation by -60 and add both equations. Then solve for "s":
Substitute s=65 into any of the original equations and solve for "l":
Given:
The expression is:
To find:
The resulting polynomial in standard form.
Solution:
We have,
Write subtraction of a polynomial expression as addition of the additive inverse.
Rewrite terms that are subtracted as addition of the opposite.
Group like terms.
Combine like terms.
On simplification, we get
Write the polynomial in standard form.
Therefore, the required polynomial in standard form is .
