Answer:
2/16
Step-by-step explanation:
i just doubled he equation
Let x be the width of the sidewalk and the area becomes:
A=LW and L=6+2x and W=4+2x now we have
A=(6+2x)(4+2x) and we are told that A=48ft^2
48=24+20x+4x^2
4x^2+20x-24=0
4(x^2+5x-6)=0
x^2+5x-6=0
x^2-x+6x-6=0
x(x-1)+6(x-1)=0
(x+6)(x-1)=0
So x=-6, 1, however since x is a measurement it must be positive thus
x=width=1 ft is the only possible solution.
I won't tell you the answer but I'll tell you how to do it
first, find the area of the rectangle (lxw)
Next, find area of the triangle (BxHx.5)
Then, subtract the area of the rectangle to the area of the triangle

<h3>What is a slope?</h3>
The slope of a graph describes how steep the graph is. It can be used to show the relationship between variables.
If we interchange the positions of the dependent and the independent variables, the meaning of the slope is retained in the case of; "as the time spent swimming increases, the number of calories burnt increases".

Answer:
Step-by-step explanation:
Any 4 sided figure closed and convex, has interior angles that add to 360 degrees
x + x + 3x + 3x = 360 Combine all like terms on the left.
8x = 360 Divide both sides by 8
8x/8 = 360/8
x = 45
The value of x is 45.
