Answer:

f(x) x^3 - 2x^2 + 5x + 12

Step-by-step explanation:

Next time please share the goal. I'm guessing your intent was to multiply out the given function.

f(x) = (x^2 + x - 3x - 3)(x - 4), or

= (x^2 - 2x - 3)(x - 4)

Now apply the distributive property of multiplication:

f(x) = x^3 - 4x^2 - 2x^2 + 8x - 3x + 12, or

= x^3 - x^2(4 - 2) + x(5) + 12, or

f(x) x^3 - 2x^2 + 5x + 12

Answer: There are 3.5 ounces of chocolate drips that Carlita need.

Step-by-step explanation:

Since we have given that

Number of pounds of turkey = $2\dfrac{1}{2}=\dfrac{5}{2}$

Since the cherries are $\dfrac{1}{4}$ equal to the turkey.

So, it becomes,

Number of pounds of cherries is given by

$\dfrac{1}{4}\times \dfrac{5}{2}\\\\=\dfrac{5}{8}\\\\=0.625$

Since the chocolate drips are 0.35 equal to the cherries.

So, the number of pounds of chocolate drips is given by

$0.625\times 0.35\\\\=0.21875\ lb$

Since 1 pound = 16 ounces.

So, Number of ounces of chocolate drips would be

$0.21875\times 16\\\\=3.5\ ounces$

Hence, there are 3.5 ounces of chocolate drips that Carlita need.

Answers:

First box = 864

Second box = 3136

=================================================

Explanation:

The weird looking E symbol is the greek uppercase letter sigma which stands for "sum". You'll be adding everything in the x^2 column to find that 64+144+256+400 = 864, which is already done for you in the table (as the 864 is at the bottom of the second column, in the "total" row).

In short, you just copy the 864 into the first box.

-------------

For the second box, you'll square the 56 to get 3136

This is because the table shows that adding up all the x values leads to 56

(8+12+16+20 = 56)

So that means $\sum x = 56$ and $\left(\sum x\right)^2 = (56)^2 = 3136$
