Answer:

(x - 2)(x + 2)

Step-by-step explanation:

If this is a difference of squares, it factors like this.

(x - 2)(x + 2)

The general rule is x^2 - a^2 factors into sqrt(x^2) +/- sqrt(a^2)

That always produces 2 factors: (x + a)(x - a)

What's the total Cents?
saveliy_v [14]

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

Let's see...

Step-by-step explanation:

  • The first coin is a quarter.
  • The second, third, fourth, and fifth coins are dimes.
  • The sixth, seventh, and eighth coins are nickels.

That being said, what is the total value of the cents?

cents    =  ¢

<u>Values:</u>

Quarter = 25 ¢

Dime     = 10 ¢

Nickel   = 5 ¢

So,

1 quarter + 4 dimes + 3 nickels    = total cents

25 + 10 + 10 + 10 + 10 + 5 + 5 + 5 = total cents

25 + 40 + 5 + 5 + 5                       = total cents

25 + 40 + 15                                  = total cents

25 + 55                                         = total cents

80                                                  = total cents

<h3><em>Our answer is 80¢</em></h3><h3><em /></h3>

I hope this helps!
