(f+g)x = f(x)+g(x)

Therefore,

\frac{x}{4}  - 3 +  {4x}^{2}  + 2x - 4 \\ 4 {x}^{2}  + ( \frac{x}{4}  +  \frac{8x}{4} ) - 7 \\ 4 {x}^{2}  +  \frac{9x}{4}  - 7

Therefore, the answer is B.

Answer:

A = 3

B = -5

C = 2

Step-by-step explanation:

The way to format a quadratic equation is: ax^2 + bx + c, so the first step to solving this is to format it in the right way, where the x^2 comes first, the x second, and the number alone.

After formatting, your equation should look like this: 3x^2 - 5x + 2

From here, you can see the the <em>a </em> is 3, the <em>b</em> is -5, and the <em>c </em>is 2

vova2212 [387]

Based on the simple interest amount he could be making, and the rate of investment, Tyrell's additional interest per month is $1,000.

<h3>How much is Tyrell paying in additional interest?</h3>

Assuming the additional interest that Tyrell is paying is x, the following formula can be used:

300 = (x × 2.5%) x 12 months

Solving gives:

300 = 0.025x × 12

0.025x = 300/12

x = 25 / 0.025

x = $1,000
