Answer:

(p - r)(pq - r)

Step-by-step explanation:

P = p²q + r² – pqr – pr  

Rewrite the equation in descending orders of p and increasing orders of r.

P = p²q - pqr - pr + r²

Factor the first two and the last two terms

P = pq(p - r) - r(p - r)

Remove the common factor

P = (p - r)(pq - r)

Please help and explain the question is in the picture
Digiron [165]

Answer: 123 square feet

Step-by-step explanation: The question is a little odd, but I can break it down easily. It wants us to find the area of a three foot border around his room.

First, the whole area of his room is 20 x 24 = 480

Next, we have to make the measurements 3 feet smaller on each wall, so 17 x 21 = 357

Finally, to find the area of the border, we simply do 480 - 357 = 123

He needs to buy 123 square feet of carpeting

Hope this helps!

X = y−4, 2x−5y = 3
dalvyx [7]
X=y-4 Let's make this eqn 1 and

2x-5y=3 this eqn 2..


Two things are possible here...
Its either you substitute for x in equation 2... Or you substitute for y...

x=y-4 put this in the equation 2..

2x-5y=3.. Replace the x with (y-4)

2(y-4)-5y = 3...
Since this is In the option no point in substituting for y...

Hope this helped...?
