Q. Rewrite in simplest terms: 7(−7n+6p)+0.9p−8(−8p−5n)Answer:
Distribute 7: Distribute the 7 into the terms inside the first set of parentheses.7×(−7n)+7×(6p)=−49n+42p
Distribute −8: Distribute the −8 into the terms inside the second set of parentheses.−8×(−8p)−8×(−5n)=64p+40n
Combine distributed terms: Combine the distributed terms with the remaining term 0.9p. −49n+42p+0.9p+64p+40n
Combine like terms: Combine like terms by adding the coefficients of the same variables.Combine the n terms: −49n+40n=−9nCombine the p terms: 42p+0.9p+64p=106.9p
Write final expression: Write the final simplified expression.−9n+106.9p
