Answer: -4a^2+3ab^2-3ab-3b^2

Step-by-step explanation:

\left(-a^2-5ab+3ab^2\right)-\left(3a^2-2ab+3b^2\right)

=-a^2-5ab+3ab^2-\left(3a^2-2ab+3b^2\right)

=-a^2-5ab+3ab^2-3a^2+2ab-3b^2

=-4a^2+3ab^2-3ab-3b^2

The correct answer is 4a^2 + 3ab

In order to find this, we can write the equation out as described and then follow the order of operations.

3a^2 - 2ab + 3b^2 - (-a^2 - 5ab + 3b^2) ----> Distribute the negative

3a^2 - 2ab + 3b^2 + a^2 + 5ab - 3b^2 ----> Combine like terms

4a^2 + 3ab

Gina takes classes at both Westside Community College and Pinewood Community College. At Westside, class fees are $98 per credit
Kipish [7]

Answer: second option.

Step-by-step explanation:

Let be "w" the credit hours at Westside Gina is taking.

You know that class fees are $98 per credit hour at Westside, then the expression for the dollar amount she paid for her class fees at Westside is:

98w

Since she is taking a combined total of 13 credit hours at the two schools, the credit hours at Pinewood Gina is taking can be represented by this expression:

13-w

You know that class fees are $115 per credit hour at Pinewood, then the dollar amount she paid for her class fees at Pinewood can be expressed as:

115(13-w)

Therefore, the expression for the combined total dollar amount she paid for her class fees is:

total\ paid=98w+115(13-w)\\\\total\ paid= -17w + 1495
