Answer:

not a solution

Step-by-step explanation:

Substitute p = - 2 into the left side of the equation and if equal to the right side then it is a solution.

7(- 2) - 5 = - 14 - 5 = - 19 ≠ 20

Find the product. (x-3)^2

r-ruslan [8.4K]

Greetings and Happy Holidays!

Find the Product:
$(x-3)^2$

Expand:
$=(x-3)(x-3)$

Use FOIL or other techniques to solve binomial multiplication:
$=x(x-3)-3(x-3)$

$=x^2-3x-3(x-3)$

$=x^2-3x-3x+9$

Combine like terms:
$=x^2-6x+9$

The Answer Is:
$\boxed{=x^2-6x+9}$

I hope this helped!

Lydia wrote 4 1/2 pages of her science report in one hour. what was her writing rate in pages per minute?

Firdavs [7]

To solve this question, I first converted one hour into minutes. (60 minutes)

Then I divided 4 1/2 into 60. As a decimal, the answer if 0.075. If you convert that into a lowest terms fraction, you get 3/40.
