Answer:

Perimeter = 32 and Area = 55

Step-by-step explanation:

There is not really an equation for perimiter you just add all the sides together and this is 32. However, for area, you need to multiply length times width and this equals 55.

Answer:

$x^2+8x+12$

Step-by-step explanation:

The area of a rectangle formula is length times width.

The length of this rectangle is $(x+2)$ , and the width of this rectangle is $(x+6)$

Thus, the area of the rectangle is $(x+6)(x+2)$ . This can be expanded using FOIL.

First $x(x)=x^2$

Outer $x(2)=2x$

Inner $6(x)=6x$

Last $6(2)=12$

The two x terms combine, making 8x, and the answer is $x^2+8x+12$

A quantity b varies jointly with c and d and inversely with e. When b is 18, c is 4, d is 9, and e is 6. What is the constant of

Fantom [35]

B $\alpha$ $\frac{cd}{e}$
b= $k \frac{cd}{e}$
Where k is a constant of proportionality.
b=18, c=4,d=9, e=6
Finding the value f k,
18= $\frac{k*4*9}{6}$
6k=18
k=3
The equation then is;
b= $\frac{3cd}{e}$
The constant of variation=3
