Add.<br> 4x^2 - 6x +3<br> 2x^2+7x-8
pantera1 [17]

Answer:

6x^2 + 2x - 5 (Option C)

Step-by-step explanation:

1. First, add 4x^2 and 2x^2 together (which is 6x^2). You can figure this out by adding 4 and 2.

2. Second, add -5x and 7x (which is 2x)

3. Lastly, subtract 3 and 8, which is -5

WHY DOES THE ANSWER HAVE A NEGATIVE 5?

The equation looks like this: +3 + -8

You are adding 3 to -8, which is the same as subtracting positive 3 and positive 8 (positive times a negative is a negative or a minus sign)

Mrrafil [7]
You can set it up like a proportion:

\frac{11000}{0.85}    \frac{x}{1.00}

Cross multiply: 
11000*1 = 11000
11000/0.85 = 12,941.18

You had roughly $12,941.18 in your bank account.
