Answer:

Step-by-step explanation:

The only one you can eliminate on sight is C. You are going to get an x^3 somewhere along the line.

You can eliminate D on sight as well. The x^3 term is 12x^3 not 7x^3

Doesn't leave much does it?

(3x + 2)(4x^2 - 2x - 7)

3x: 12x^3 - 6x^2 - 21x

2 : 8x^2 - 4x - 14

======================= Add

12x^3 + 2x^2 - 25x - 14

Blake and James are planning to go on a trip. Blake already has some money saved. She earns $96 more by working overtime. James

Blake saved $\bold{\$ 433.80}$

Option - A

<u>SOLUTION: </u>

Given, Blake and James are planning to go on a trip.

Blake already has some money saved.

Let the amount saved by Blake be $\$ n$ .

She earns $\$96$ more by working overtime.

Then, total amount by Blake $=\$(n+96)$

James has $\$ 53$ more than 4 times the amount of money that Blake has saved.

Then, total amount by James will be $\$ 53+4 \times \$ n=\$(4 n+53)$

If they have $\$2,318$ in all, we have to find how much money had Blake originally saved

Now, total amount = $\$2318$

$\begin{array}{l}{\rightarrow \text { Amount by Blake }+\text { amount by James }=2318} \\\\ {\rightarrow \mathrm{n}+96+4 \mathrm{n}+53=2318 \rightarrow 5 \mathrm{n}+149=2318 \rightarrow 5 \mathrm{n}=2318-149 \rightarrow 5 \mathrm{n}=2169 \rightarrow \mathrm{n}=433.8}\end{array}$
