Answer:
These equations are incomplete so I cant solve it
Step-by-step explanation:
1-No
2-Yes
3-Yes
4-No
5-No
Hope this helps!!!! :)
P = 2(L + W)
P = 112
L = 35
112 = 2(35 + W)
112 = 70 + 2W
112 - 70 = 2W
42 = 2W
42/2 = W
21 = W <=== width is 21 inches
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.
Its A because my class is litterally studing that now
