Let X be the width of the path.
The width of the path would be the width of the pool plus 2x, so 2x +16
The length of the path would be the length of the pool plus 2x, so 2x+22
The total area is 832 square feet.
Area is found by multiplying the length by the width.
So you have:
(2x+16) (2x+22) = 832
Use the Foil Method:
(2x+16) (2x+22) = 4x^2 +76x+352
Now you have:
4x^2 +76x+352 = 832
Subtract 832 from both sides:
4x^2 +76x+352-832 = 0
Simplify:
4x^2 +76x -480
Factor the left side:
4(x-5)(x+24) = 0
Divide both sides by 4:
(x-5)(x+24) = 0
Set both parenthesis to equal 0 and solve for x:
x=5 and x = -24
The width of the path cannot be a negative number, so the width is 5 meters.
Answer:
Is there supposed to be a worksheet attached but im guessin it's 8
Step-by-step explanation:
I believe the answer is
26
sorry if wrong
if not an answer choice then 168.
If x is twice that of y, then x = 2y forming one possible equation. This plots a straight line through the points
(0,0)
(2,1)
(4,2)
etc etc. Basically whatever y is, double it to get x
Another possible equation is y = 2x which is a straight line through the points
(0,0)
(1,2)
(2,4)
etc. The flip of the other list of points above.
Because it is not clear which coordinate is doubled, we can't say for sure which equation we'll pick. However, we only pick one equation. This one equation produces only one line that splits the xy plane into two parts. So there are 2 regions.
Answer:
The equation of the line in point slope form is equal to
Step-by-step explanation:
The picture of the question in the attached figure
step 1
Find the slope
The formula to calculate the slope between two points is equal to
