The original expression is 2(a+5) + 4(2a+3) - 10.
Using the Distributive Property:
= 2a + 10 + 8a + 12 - 10
Combine like terms:
= 10a + 22
Thus, the equivalent expression using the Associative and Commutative Properties is 10a + 22.
Apply the Associative and Commutative Properties to generate an expression equivalent to 2(a+5)+4(2a+3)−10 .
10a +22
9a +12
10a +12
