-5(m-4n-5)-3

7(p-6q8)-4

13

= 222q^8 - 5m + 20n -37 + 21

Step-by-step explanation:

−5(m−4n−5)−37(p−6q8)−4

step 1  

=(−5)(m)+(−5)(−4n)+(−5)(−5)+(−37)(p)+(−37)(−6q8)+−4

=−5m+20n+25+−37p+222q8+−4

step 2

=−5m+20n+25+−37p+222q8+−4

=(222q8)+(−5m)+(20n)+(−37p)+(25+−4)

=222q8+−5m+20n+−37p+21

for b its (t) and c its (d)
