Can someone help me out with some math?

1 answer:

8 0

81x^2 - 4y^2 Note this is the difference of 2 perfect squares

a^2 - b^2 = (a + b)(a - b)

so here we have a = 9x and b = 2y

and our factors are

(9x + 2y)(9x - 2y)

the dimensions are 9x + 2y and 9x - 2y

Draw and label a net to find the surface area of the original juice box. it costs

3241004551 [841]

Based on the area of the juicebox and the cost per square inch, the cost to create one package is $7.20.

<h3>What is the cost of one package?</h3>

First, find the area of the juice box. The formula is:

= 2lh + 2lw + 2hw

= (2 x 3 x 4) + (2 x 3 x 1.5) + (2 x 4 x 1.5)

= 45 inch²

The Cost is $0.02 per square inch and the number per package is 8 juice boxes. The total cost is:

= 45 x 0.02 x 8 boxes

= $7.20

Reduce the fraction to lowest terms. Do not us<br>- 5jk/35j2k2

pychu [463]

Answer:

$-(7jk)^{-1}$

Step-by-step explanation:

(Interpreting equation as)

$\frac{-5jk}{35k^2k^2}$

We can reduce the fraction by dividing the top and the bottom by terms they have in common.

First, lets rewrite both the numerator and denominator in terms of each other.

$\frac{-5jk}{35j^2k^2}=\frac{(-1)(5jk)}{(7jk)(5jk)}$

If you expand the fraction, you will get exactly what you start with, now this is fine.

As we can see both halves of the fraction have a common term ( $5jk$ ), so we can divide by this - and the fraction will still be equivalent to as it was before
