The width of a rectangle is 3 3 feet longer than two times its length, and its area is 27 27 . If you use L L to represent the l
Nady [450]

Answer:

The expression representing the width is 3+2L

The width is 9ft

Step-by-step explanation:

Area of a rectangle = Length×width

A = L × W...(1)

Let the length be represented as L

Since the width of the rectangle is 3feet longer than two times its length, this is expressed as:

First, width is twice as long as the length i.e W = 2L

If the resulting width is now 3 feet longer, the final width of the rectangle will be expressed as:

W = 3+2L...(2)

Area (A) = 27ft

Substituting equation 2 into 1, we have;

A = L(3+2L)

A = 3L+2L²

27 = 3L+2L²

2L²+3L-27 = 0

Factorizing the resulting equation

(2L²+9L)-(6L-27) = 0

L(2L+9)-3(2L+9) = 0

L-3 = 0 and 2L+9 = 0

L = 3 and L = -9/2

Disregarding the negative value and substituting L = 3 into equation 2 to get the width

W = 3+2(3)

W = 3+6

W = 9ft

Find n(A) for the following set. <br> A={a,b,c,...,z}
MariettaO [177]

n(A) = 26

Solution:

Let us first define the cardinal number of the set.

Cardinal number of the set:

The number of distinct elements in a finite set is called its cardinal number. It is denoted as n(A).

Given set: A = {a, b, c, .... z}

We know that, there are 26 elements in the alphabet "a to z".

Number of elements in the set A = 26

Hence n(A) = 26.
