Question

Simplify using the distributive property: 2a + 4(a+5) - 7

Answer 1

Answer: 6a + 13

Step-by-step explanation: here you go: 2a + 4*(a+5) - 7

first we simplify the brackets (distributive property, you multiply 4 "a" times plus 5 times): 2a + 4a + 20 - 7

then you add those that multiply the variable separately from those that don't: 6a + 13

Answer 2

Answer:

6a + 13

Step-by-step explanation:

Given

2a + 4(a + 5) - 7 ← distribute parenthesis

= 2a + 4a + 20 - 7 ← collect like terms

= 6a + 13
