How do you combine #6( 3- 3a ) - 8( 6a + 5) #?

Answer 1

Avery Alexander

#-66a - 22#

Given the phrase,

#6(3-3a) - 8(6a + 5)#

We obtain,

#6(3-3a) - 8(6a + 5) = color(blue) (18) - color (red) (18a)

color(red) (48a) - color(blue) (40) = color(red) (-66a) color(blue) (-22) #

To combine the expression 6(3 - 3a) - 8(6a + 5):

First, distribute the coefficients: 6(3) - 6(3a) - 8(6a) - 8(5)

Then, perform the multiplication: 18 - 18a - 48a - 40

Now, combine like terms: (18 - 40) - (18a + 48a) = -22 - 66a

Therefore, the combined expression is -22 - 66a.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
