Correct answer is A.

(x^2+4x-3)(2x^2+x+6)
\\=x^2(2x^2+x+6)+4x(2x^2+x+6)-3(2x^2+x+6)
\\=2x^4+x^3+6x^2+8x^3+4x^2+24x-6x^2-3x-18
\\=2x^4+x^3+8x^3+6x^2+4x^2-6x^2+24x-3x-18
\\=2x^4+9x^3+4x^2+21x-18

What is tje equation of the function?
crimeas [40]

Answer:

It is relatively easy to determine whether an equation is a function by solving for y. When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x.

A number d minus is less than -1
katrin [286]

\boxed{d-4

<h2>Explanation:</h2>

Hello! Recall you need to write complete questions in order to find exact answers. So in this problem I'll assume the question is:

<em>A number d minus 4 is less than -1</em>

<em />

So it is easy to know that we need to write an inequality here because of the words "less than", which implies that we must use the symbol <. So let's solve this step by step.

Step 1. A number d minus 4.

This statement includes the word "minus", so we need to use the symbol (-). Therefore:

d-4

Step 2. A number d minus 4 is less than

As we said above, here we need to use the symbol (<). So:

d-4

Step 3. A number d minus 4 is less than -1

Finally, we get:

d-4

Jake bought 3 drawing pens for $8.07. Each pen costs the same amount. About how much did he spend for one pen? * 2 points
Marina86 [1]

Given:

Jake bought 3 drawing pens for $8.07.

Each pen costs the same amount.

To find:

How much did he spend for one pen?

Solution:

Let x be the cost of each pen. Then

Cost of three pens = 3x

Jake bought 3 drawing pens for $8.07.

3x=8.07

Divide both sides by 3.

x=\dfrac{8.07}{3}

x=2.69

Therefore, he spend $2.69 for one pen.
