The area of a rectangle is 28 square inches.If the length is 4 inches, what is the perimeter of this rectangle?

Answer:

Perimeter of the rectangle, P = 22 inches

Step-by-step explanation:

Let A represent the area, L , the length, W , the width and P, the perimeter of the rectangle

Area of a rectangle, A = LW ....eq 1

Perimeter of a rectangle P = 2 ( L + W ) ....eq 2

A = 28 sq inches

L = 4 inches

Slotting in the values of A and L in eq 1

28 = 4W

28/ 4 = 4W / 4

7 = W

Therefore, W = 7 inches

Now, lets slot in the values of W and L in eq 2

P = 2 ( 4 + 7 )

P = 2 ( 11 )

P = 22 inches

Answer:

Step-by-step explanation:

If x represents an even number, which expression represents an odd number? a. x to the second power

b. x+3

c. 3x

d. x/3

Can someone please help me

Test the choices !

Pick an even number, and see what each choice does to it.

Let's start with, say, 6 .

We'll try each choice, and see which one produces an odd number:

a). 6 to the 2nd power. . . . . . 6 x 6 = 36. That's not an odd number.

b). 6 + 3 = 9 This could be it. 9 is odd. We'll save this one.

c). 3·6 = 18. That's not an odd number.

d). 6/3 = 2. That's not an odd number.

The only one that gave us an odd number is (b).

Use the definition of division to find each quotient, if possible. If a quotient is not defined, explain why 0÷(-6)

0 / -6

zero can be divide as many times as you want

so its 0

Write 3.48 repeating as a fraction and write 1.07 repeating as a fraction

For the number 3.48 we have:

We multiply and divide the number by 100:

We simplify the fraction obtained.

Answer:

3.48 repeating as a fraction is:

For the number 1.07 we have:

We multiply and divide the number by 100:

The fraction obtained can not be simplified because we do not have multiples of the numerator and denominator equal.

Answer:

1.07 repeating as a fraction is:

Use the function g(x) = -x+2 with initial values of 4, 2, and 1. What happens after many iterations with all three initial values? How do the results of all three iterations relate to each other?

Answer:

The given function is , g(x)= - x + 2

For values of , is the sequence, -2,4,-2,4,-2,4........

For values of , is the sequence, 0,2,0,2........

For values of , is the sequence, 1,1,1,1,........

For initial value, of 4,the sequence converges to two values that is -2, 4.

For initial value of 2, the sequence again converges to two values which are 0,2.

For initial value of 1, the sequence converges to one value which is 1.

→→First Iterative value that is (-2)=Second iterative value (0) + 2 ×Third iterative value(1)

→→ First Iterative value that is (4)=Second iterative value (2) + 2 ×Third iterative value(1)
