Answer: 497

Step-by-step explanation:

The formula for this sequence is (x+6), and since the first three terms are given, you only need to find the last 84 terms.

Multiply 6 by 84

6 * 84 = 504

Now subtract 7 from 504 since -7 is the third term.

504 - 7 = 497

the length of a rectangle is 6 inches longer than its width. If the perimeter of the rectangle is 76in. Find its length and widt
DerKrebs [107]

The length and the width of the rectangle are 22 inches and 16 inches respectively

<h3>How to determine the length and the width of the rectangle?</h3>

The given parameters are:

Length = 6 inches + width

Perimeter = 76 inches

The perimeter is calculated as:

Perimeter = 2 * (Length + Width)

This gives

76 inches = 2 * (6 inches + Width + Width)

Divide through by 2

38 inches = 6 inches + Width + Width

Evaluate the like terms

2 * Width = 32 inches

Divide both sides by 2

Width = 16 inches

Substitute Width = 16 inches in Length = 6 inches + width

Length = 6 inches + 16 inches

Evaluate

Length = 22 inches

Hence, the length and the width of the rectangle are 22 inches and 16 inches respectively
