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.
Soryy about this late.
I think the Answer should be :36π yd
Answer: Non linear
Step-by-step explanation:
x is increasing steadily at a constant rate however the change in the y values vary from x values and they are not constant so this line is non linear
Answer:
17/30 pi
Step-by-step explanation:
To convert from degrees to radians, multiply by pi/180
102 * pi/180
102/180 * pi
17/30 pi

For

the value of

is negative, and for

the value is positive which means between

and

there is an x for which the value of

is equal to 0 and therefore there is a solution.
