The length of a rectangle is the width minus 3 units. The area of the rectangle is 40 units. What is the width, in units, of the
1 answer:
The width of rectangle is 8 units.
Step-by-step explanation:
Given,
Area of rectangle = 40 units
Width = w
Length = w-3
Area = Length * Width
Factorizing the equation
Either,
w-8=0 => w=8
Or,
w+5=0 =>w= -5
As width cannot be negative, therefore
Width of rectangle = 8 units
The width of rectangle is 8 units.

Equilateral
equi means equal
lateral means sides
all sides are equal
triangle has 3 sides
perimiter=side1+side2+side3
side1=side2=side3
area=1/2 times base times height
base=side
draw a line down the middle of te tiangle so you get 2 right triangles side by side
1/2base is one leg
base is hypotonuse
height is unknown
equilateral means that it is a 30-60-90 triangle with hypotonuse equal to 2x, height=x√3, bottom is x
1/2 times base times height=1959
1/2 times x times x√3=1959
multiply both sides by 2
(x^2)√3=3918
divide both sides by √3
x^2=3918/√3
square root both sides
x=47.5611
side=hypotonuse=2x
2x=2*47.5611
side=95.12222
