Answer:
6x^2-5x+1
Step-by-step explanation:
Use the foil method:
multiply 2x with 3x and -1.
then multiply -1 with 3x and -1
when multiplied, you should have gotten 2x×3x=6x^2, then 2x×-1, then -1×3x=-3x, then you put all of the answers in order from variables with exponents to normal variables to non variables
First, you need to get rid of the parenthesis, so you need to distribute:
12(–1.4m + 0.4) = m + 0.2
-16.8m + 4.8 = m +0.2
Then subtract both sides by m:
-16.8m - m + 4.8 = m +0.2 - m
-17.8m + 4.8 = 0.2
Subtract both sides by 4.8:
-17.8m + 4.8 - 4.8 = 0.2 - 4.8
-17.8m = -4.6
Now, divide both sides by -17.8:
-17.8m/-17.8 = -4.6/-17.8
m ≈ 0.258
The cheaper car service would be the second option, $10 upfront + $.05 per mile.
$4+$.70(12 miles)= $12.40
$10=$.05(12 miles)= $10.60
Hope this helps you! :D
When you are doing distribution with this problem you are going to get your answer of....
D) 12x^2 - 13x - 14
Steps:
Simplify...
<span>(3x + 2)(4x - 7)
= (3x + 2) (4x + -7)
= (3x)(4x) + (3x)(-7) + (2)(4x) + (2)(-7)
= 12x^2 - 21x + 8x - 14
=12x^2 - 13x -14</span>
