Question

Need help simplifying algebraic expressions. -2d+3(-7d+9)

if you simplify the algebraic expression you would get -23d+27

Answer 2

-2d + 3(-7d + 9)...distribute the 3 thru the parenthesis
-2d - 21d + 27.....combine like terms
-23d + 27 <====

let me break the distribution down for u....ur basically multiplying the 3 by everything in the parentheses...to get rid of the parenthesis
3(-7d + 9) = (3 * -7d) + (3 * 9) = -21d + 27
