Answer:
volume = 339292 cubic inch
Step-by-step explanation:
To answer this question you must first plug in the given value for x into your given expression.
Your given x value is a -3.
When plugged in, this leaves you with:
-3^2 + 4(-3) + 3
Next, follow PEMDAS (parenthesis, exponents, multiplication, division, addition, subtraction) to begin to simply your expression.
Start by multiplying the parenthesis, this leaves you with:
-3^2 - 12 + 3
After that, simplify your exponents by squaring the -3. You do this by multiplying it by itself.
This leaves you with:
9 - 12 + 3 (the 9 is positive because the two negative multiplied together cancelled to make a positive)
Finally, simplify across with addition and subtraction to get your final answer.
This results in:
0
So, when x = -3 in this expression, the answer is 0.

<u>Answer:</u>
x² - 10x + 25
<u>Step-by-step explanation:</u>
The formula for squaring any binomial (an expression with two terms) is:
(a ± b)² = a² ± 2ab + b²
Let a = x and b = 5.
∴ Substituting:
(x - 5)² = x² - 2(x)(5) + (-5)²
= x² - 10x + 25
The distance between the two is 16.
This is because we know that they y coordinates are the same, so then all we need to know is the difference between the two x coordinates. In this case, all we have to do is subtract 4 from 20.
Hope that this helped.
