-4p³+3p²-17p

Step-by-step explanation:

(-3p³+5p²-2p)+(-p³-8p²-15p)

-3p³+5p²-2p-p³-8p²-15p

-3p³-p³+5p²-8p²-2p-15p

=-4p³+3p²-17p

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
