The length of a rectangle can be found using the following formula.

what is the length of a rectangle that has a width of 2.5 centimeters and an area of 20.5 square centimeters?

Length = 8.2 cm

Step-by-step explanation:

A = length * width

length = A / width

length = 20.5 / 2.5

length = 8.2 cm

Check:

A = length*width

A = 8.2 * 2.5

A = 20.5 cm^2

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
