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:

Step-by-step explanation:

Factoring an expression is the process of undoing the multiplication.

Assume you have a function f(x):

$f(x)=x^2+2x-48$

This can be factored:

$f(x)=(x+8)(x-6)$

Using multiplication and the distributive property, you arrive back to:

$f(x)=x^2+2x-48$

Then you can see clearly that all we've done is reverse the multiplication.
