It's already in the simplest form.

The answer would stay the same as the question (3x^2 + 2x).

This is because the variables can't be added together because they are not the same (x^2 not equal to x). So, the answer would stay the same

Calculate the value of V when P=480

nadezda [96]

Answer:

v is 120

Step-by-step explanation:

Choose the correct simplification of the expression (3x)^4.

Y_Kistochka [10]

The exponent 4 needs to be applied to both 3 and x, so we would have:
3 * 3 * 3 * 3 * x^4.
9 * 9 * x^4.
81x^4

A supply company manufactures copy machines. The unit cost C (the cost in dollars to make each copy machine) depends on the numb

ArbitrLikvidat [17]

Answer:

$9327

Step-by-step explanation:

Apparently, the cost function is supposed to be ...

C(x) = 0.4x^2 -112x +17167

This can be rewritten to vertex form as ...

C(x) = 0.4(x^2 -280) +17167

C(x) = 0.4(x -140)^2 +17167 -0.4(19600)

C(x) = 0.4(x -140)^2 +9327

The vertex of the cost function is ...

(x, C(x)) = (140, 9327)

The minimum unit cost is $9327.

_____

<em>Comment on the question</em>

You found the number of units that result in minimum cost (140 units), but you have to evaluate C(140) to find the minimum unit cost.
