The diagram shows the space for the new development.

Ni-
mile
Usha thinks that the area of the development will be greater than the total area of
50 football pitches
Usha knows
a football pitch is rectangular 100 m by 50 m
I mile - 1600 m.
a) Will the area of the development be greater than the total area of
50 football pitches?
The show reverse calculation to show answer is correct

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
