Answer:
x^3 - x^2 - 6x
Step-by-step explanation:
First, add f +g
x^2 + 1 + 5 -x (combine like terms)
x^2 - x +6
Next, multiply the new equation by x
x(x^2 - x + 6) Use distributive property
= x^3 - x^2 + 6x
Answer:
The perimeter of the square is 
Step-by-step explanation:
step 1
Find the length side of the square
we know that
The area of a square is equal to

where
b is the length side of the square
we have

substitute and solve for b

square root both sides

step 2
Find the perimeter of the square
we know that
The perimeter of the square is equal to

we have

substitute


Answer:

Step-by-step explanation:
The first step is to combine the parts of the numerator and denominator into one rational expression each. Those will have the same denominator, so their ratio is the ratio of their numerators.

136×25%=136×25/100= 3 400/100=34
so the markeup value is
136+34= 170
170×17%=170×17/100=2 890/100=28.9
170-28.9=141.1
Selling price=136+170=306
Answer:
y =
x + 1
Step-by-step explanation:
Slope is rise over run, or the vertical progression over the horizontal progression.
Your example has a line that heads downwards, so we know that the slope is negative. If we count the squares, the "rise" is down by 4. We count the squares going horizontally and there are 5. So, your slope is
.
The other half of the equation is the y-intercept, or where the line crosses the y axis. It appears to be at (0 , 1), so we can say that your y-intercept is 1.
