The area of a rectangle is 20. The length is 3 less than twice the width. Find the length and the width
SIZIF [17.4K]

The length of rectangle is 5 units and width is 4 units.

Step-by-step explanation:

Given,

Area of rectangle = 20

Width of rectangle = w

Length of rectangle = 2w-3

Area = Length * Width

20=(2w-3)(w)\\20=2w^2-3w\\2w^2-3w-20=0

Factorizing

2w^2-8w+5w-20=0\\2w(w-4)+5(w-4)=0\\(2w+5)(w-4)=0

Either;

2w+5=0         =>2w=-5

Or,

w-4 = 0           => w=4

As width cannot be negative, therefore,

width of rectangle = 4 units

length of rectangle = 2w-3 = 2(4)-3 = 8-3 = 5 units

The length of rectangle is 5 units and width is 4 units.

For the function f(x) = x + 7, what is the ordered pair for the point on the graph when x = 2b?
zalisa [80]

Answer:

The ordered pair is the point (2b,2b+7)

Step-by-step explanation:

we have

f(x)=x+7

For x=2b

Substitute the value of x in the function

so

f(2b)=2b+7

therefore

The ordered pair is the point (2b,2b+7)
