First, apply the distributive property:
2(a+5) + 4(2a+3) - 10 = 2a + 10 + 8a + 12 - 10
Now, use the commutative property to rearrange the terms:
2a + 10 + 8a + 12 - 10 = 2a + 8a + 10 + 12 - 10
Use the associative property to group the like terms:
2a + 8a + 10 + 12 - 10 = (2a + 8a) + (10 + 12 - 10)
Combine the like terms:
10a + 12
The equivalent expression is 10a + 12.
Apply the Associative and Commutative Properties to generate an expression equivalent to 2(a+5)+4(2a+3)−10.(1 point)
