I think you left a bracket which is really important for rhe solution but,these are the possible solutions depending on the bracket.Sorry if I made any mistakes
4p^3(p^2 +8p-3)
=4p^5+32p^4 - 12p^3

(or)
4p^3(p^2) +8p-3
=4p^5+8p-3

TMI, a manufacturer of blank DVDs, has a monthly fixed cost of $14,200 and a variable cost of 70 cents/disc.

Svetllana [295]

Answer: Therefore, the total cost incurred per month is;

C(x) = 14,200 + 0.7x dollars

Step-by-step explanation:

Given;

Fixed cost Cf = $14,200 per month

variable cost = 70cent/disc

Number of disc manufactured per month = x disc/month.

The total variable cost in a month can be given as;

Cv = 70cent/disc × x disc/month

Cv = 70x cent/month × 1/100cent/dollar

Cv = 0.7x dollar/month

Total cost C = Fixed cost + variable cost

C = Cf + Cv

Substituting the values, we have;

C(x) = 14,200 + 0.7x dollars/month

Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms.

jekas [21]

Option A

$\frac{12}{36} = \frac{13}{39} = \frac{1}{3}$ is the the ratio of corresponding sides for the similar triangles

<em><u>Solution:</u></em>

We have to write the ratio of corresponding sides for the similar triangles

When two figures are similar, the ratios of the lengths of their corresponding sides are equal.

The given figure in question is attached below with sides marked as ABC for bigger triangle and XYZ for smaller triangle

Therefore,

$\frac{XY}{AC} = \frac{YZ}{CB}$

In the attached figure,

XY = 12

AC = 36

YZ = 13

CB = 39

Substituting these we get,

$\frac{12}{36} = \frac{13}{39}$

Reducing to lowest terms we get,

$\frac{12}{36} = \frac{13}{39} = \frac{1}{3}$

[ 36 divided by 12 is 3 and 39 divided by 13 is 3 ]

Thus Option A is correct
