Find the equivalent expression for:
3+2(2p+4t)

Step-by-step explanation:

Given that

3+2(2p+4t)

Let open the bracket first

3+ 2×2p + 2×4t

3+4p+8t

This is the equivalent of the expression.

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
