A trinomial is a polynomial with three terms. It can be determined if it is a difference of two squares when you factor it.

The resulting factor of a trinomial that is a difference of two squares is: a²<span> – b</span>²<span> = (a + b)(a – b) or (a – b)(a + b)</span>

You will notice that the middle term is missing. This means that the middle term zeroes out as a result of having the same number of different signs (+ and -)

Let’s think about another type of scenario. What if you were told that a bracelet requires 10 beads and 10 minutes to make while

Georgia [21]

Answer:

$425

Step-by-step explanation:

Let x represent the number of bracelets made and let y represent the number of necklace made.

Since the craftsman has 1000 beads to work with, hence:

10x + 20y ≤ 1000 (1)

Also, the craftsman has 1600 minutes, hence:

10x + 40y ≤ 1600 (2)

From ploting equations 1 and 2 on the geogebra online graphing, we can see that the solution to the problem is (40, 30).

Since the bracelet costs $5 and a necklace costs $7.50, hence the maximum revenue is:

Revenue = 5x + 7.5y = 5(40) + 7.5(30) = $425

Find the percent of increase to the nearest whole from 12 to 20

ankoles [38]

Answer:

The answer is

Step-by-step explanation:

To find the percentage increase we use the formula

<h3> $Percentage \: change = \frac{change}{original \: \: quantity} \times 100\%$ </h3>

From the question

The original value = 12

To find the change we subtract the smaller value from the larger one

That's

Change = 20 - 12 = 8

So the percentage increase is

<h3> $\frac{8}{12} \times 100 \%\\ = \frac{2}{3} \times 100\% \\ = 66.67\%$ </h3>

We have the final answer as

$67\%$ to the nearest whole number

Hope this helps you
