Step-by-step explanation:
Answer:
a=8
Step-by-step explanation:
We can use ratios of similar triangles to solve
The smaller triangle has sides a and 12 and the larger triangle has sides a+a+4 and 12+18 which combine to 2a+4 and 30
a 2a +4
--------- = -----------
12 30
Using cross products
30a = 12(2a+4)
30a = 24a +48
Subtract 24a from each side
30a -24a = 24a-24a +48
6a = 48
Divide each sdie by 6
6a/6 =48/6
a =8
Answer:
A solution
Step-by-step explanation:
Just plug in you point
5 = -3(2) + 11
5 = -6 + 11 (collect like terms)
5 = 5

8 sodas X $1.59 =$12.72 per week
$12.72 per week X 4 weeks per month =$50.88
$50.88 X 12 months per year = $610.56 per year
Answer:
x^2 - 5x - 66
Step-by-step explanation:
1. Distrubute the x to the x and -11 so you will get x^2 - 11x
2. Distrubute the 6 to x and -11 and you get 6x - 66
3. Combine like terms (x^2 - 11x + 6x - 66) you will get x^2 - 5x - 66
