A Rectangular‘s perimeter and it’s area have the same numerical value. The width of the rectangle is 3 units. What is the length

of the rectangle in units?

Answer:We found that the 6 by 3 rectangle works, because 6+3+6+3=18 and 6x3=18, so this has equal area and perimeter. ... But if both the length and the width are odd, then the area will be odd, meaning that it is impossible for the perimeter to be the same as the area.

Analyze the end behavior of each function below. Then, choose one of the functions, and explain how you determined
kumpel [21]

Answer:

End behavior of a polynomial function depended on the degree and its leading coefficient.

1. If degree is even and leading coefficient is positive then

p(x)\rightarrow \infty\text{ as }x\rightarrow \infty

p(x)\rightarrow \infty\text{ as }x\rightarrow -\infty

2. If degree is even and leading coefficient is negative then

p(x)\rightarrow -\infty\text{ as }x\rightarrow \infty

p(x)\rightarrow -\infty\text{ as }x\rightarrow -\infty

3. If degree is odd and leading coefficient is positive then

p(x)\rightarrow \infty\text{ as }x\rightarrow \infty

p(x)\rightarrow -\infty\text{ as }x\rightarrow -\infty

4. If degree is odd and leading coefficient is negative then

p(x)\rightarrow -\infty\text{ as }x\rightarrow \infty

p(x)\rightarrow \infty\text{ as }x\rightarrow -\infty

(a)

f(x)=x^4

Here, degree is even and leading coefficient is positive.

f(x)\rightarrow \infty\text{ as }x\rightarrow \infty

f(x)\rightarrow \infty\text{ as }x\rightarrow -\infty

(b)

g(x)=-x^4

Here, degree is even and leading coefficient is negative.

g(x)\rightarrow -\infty\text{ as }x\rightarrow \infty

g(x)\rightarrow -\infty\text{ as }x\rightarrow -\infty

(c)

h(x)=x^3

Here, degree is odd and leading coefficient is positive.

h(x)\rightarrow \infty\text{ as }x\rightarrow \infty

h(x)\rightarrow -\infty\text{ as }x\rightarrow -\infty

(d)

k(x)=-x^3

Here, degree is odd and leading coefficient is negative.

k(x)\rightarrow -\infty\text{ as }x\rightarrow \infty

k(x)\rightarrow \infty\text{ as }x\rightarrow -\infty

A rectangle has an area of 900square inches. The length of the rectangle is 2.25 times the width.Find the dimensions
Alexeev081 [22]

Answer:

Length = 45 inches and Width = 20 inches

Step-by-step explanation:

Let the width be w.

Length(l)=2.25w

Area = 900 in^2

The formula for the area of a rectangle is Area = length * width

So substituting our values we get:

A=2.25w*w\\900=2.25w*w\\2.25w^2=900\\w^2=\frac{900}{2.25} \\w^2=400\\w=\sqrt{400} \\w=20

So we get width = 20 inches

Length = 2.25w

so Length= 2.25*20

=45 inches
