Janice is building a fence around a portion of her rectangular yard. the length of yard she will enclose is x, and the width is 2x^2-98x+5, where the measurements are in feet. if the length of the enclosed yard is 50 feet and the cost of fencing is $13 per foot, how much will janice need to spend on fencing?

We are given

length of rectangular yard is x

so,

width of rectangular yard is

so,

We are given

the length of the enclosed yard is 50 feet

so, we get

now, we can plug x=50 and then we can find width

now, we can find total fencing length

so, total fencing length is

now, we can plug values

now, we are given

the cost of fencing is $13 per foot

so,

total cost = (cost of fencing)*(total fencing length)

we can plug values

So, Janice will spend $4030.........Answer

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
