Exact dimensions:
Approximate dimensions:
Step-by-step explanation:
Let's assume width of rectangle is w ft
The length of a rectangular flower bed is 2ft longer than the width
so,
length =w+2
now, we can find area
now, we can plug it
we are given area =6
so, we can set it equal
and then we can solve for w
we can use quadratic formula
now, we can compare and find a,b and c
a=1 , b=2 , c=-6
we know that dimension can never be negative
so, we will only consider positive value

Answer:
The zero of the equation represents the maximum height attained by the shot put.
Step-by-step explanation:
William is competing in the shot put event at a track meet. The quadratic expression that models the vertical height of the shot from the ground is
H =
We can find the zeroes of these two equations.
For that put H = 0.
= 0
(-2x + 5)(x + 1) = 0
x= -1 or x = 2.5
x= -1 is neglected as it is not practical.
x = 2.5 is the maximum height attained by the shot put.
The zero of the equation represents the maximum height attained by the shot put.
