Answer: p=8

Step-by-step explanation:

4p-11=21

We move all terms to the left:

4p-11-(21)=0

We add all the numbers together, and all the variables

4p-32=0

We move all terms containing p to the left, all other terms to the right

4p=32

p=32/4

p=8

Jonas types 560 words in 20 mins. How many words can he type in one hour
dalvyx [7]

Answer:

1680 words.

Step-by-step explanation:

There are 60 minutes in an hour. So all you need to do it 560 + 560 + 560.

I say this because he types 560 word in 20 minutes..20+20+20 is 60 so that means you have to add 560, 3 times as well.


Hope this helped! :)

A square has a side length equal to 5x-3y inches. What is the area of this square
erastovalidia [21]

Answer:

D.

Step-by-step explanation:

The area is the product of 2 adjacent sides:

Area = (5x - 3y)(5x - 3y)     as the sides of a square are all equal.

= 5x(5x - 3y) - 3y(5x - 3y)

= 25x^2  - 15xy - 15xy + 9y^2

= 25x^2 - 30xy + 9y^2.
