Answer:
39x-7
Step-by-step explanation:
The perimeter is all the sides added together so
9x + 8x - 2 + 5x + 1 + 17x - 6
Since you can't solve it you just want to simplify the equation, add the like terms together
9x+8x+5x+17x = 39x
-2+1-6 = -7
Your equation is 39x-7
-9x^3-72x^2+36=3x^3+x^2-3x+8 Add 9x^3 to both sides.
-72x^2 + 36 = 3x^3 + 9x^3 + x^2 - 3x + 8 Add 72x^2 to both sides
36 = 12x^3 + 73x^2 - 3x + 8 Subtract 36 from both sides.
0 = 12x^3 + 73x^2 - 3x - 28
It does factor, but it is not very nice.
(x + 6.06)(x - 6.09)(x + 0.632)
If there is any kind of error please report it in a note below.
A)
145 - 5d
5d = 145, set equal
29 days to lay all the track
b)
5*19 = 95
145-95 = 50
After 19 days, they have 50 miles to go.
Answer:
Find out the what is the salesman's commission as a percent of his total monthly sales .
To prove
Formula
As given
A car salesman had $65,100 in total monthly sales last month. He made $1,953 in commission from those sales.
Here
Part value = $1953
Total value = $ 65100
Put in the formula
Percentage = 3%
Therefore the salesman's commission as a percent of his total monthly sales is 3% .
