Q. Rewrite in simplest terms: 4(7s−8t)+5t−5(−4t−9s)Answer:
Distribute and Calculate: Distribute the 4 into the first parentheses and the −5 into the second parentheses.Calculation: 4(7s)−4(8t)+5t−5(−4t)−5(−9s)This gives us: 28s−32t+5t+20t+45s
Combine Like Terms: Combine like terms.Calculation: 28s+45s)+(−32t+5t+20t)(This gives us: \$-7t\)
Check for Simplification: Check for any remaining like terms and simplify if possible.\(\newline\)Calculation: There are no more like terms to combine, so the expression is already simplified.
