Subtract 2p^2+3q^2-2r^2+5 from 5p^2-4q^2-7r^2-6

3p²-7r²-5r²-11

Step-by-step explanation:

(5p²-4q²-72²-6)

- (2p²+3p²-2r²+5)=

3p²-7r²-5r²-11

see below

Step-by-step explanation:

Let's sim[plify step-by-step.

5p²−4q²−7r²-6−(2p²+3q²−2r²+5)

Distribute the Negative Sign:

=5p²−4q²−7r²−6+−1(2p²+3q²−2r²+5)

=5p²+−4q²+−7r²+−6+−1(2p²)+−1(3q²)+−1(−2r ²)+(−1)(5)

=5p²+−4q²+−7r²+−6+−2p²+−3q²+2r²+−5

Combine Like Terms:

=5p²+−4q²+−7r²+−6+−2p²+−3q²+2r²+−5

=(5p²+−2²)+(−4q²+−3q²)+(−7r²+2r²)+(−6+−5)

=3p²+−7q²+−5r²+−11

=3p²−7q²−5r²−11

she will most likely have 33  

step-by-step explanation:

i think the amount would be $140.62
