The first piece is 9 feet and the second piece is 21 feet. Explanation:

We know that a 30 foot board is cut into two pieces and that the second piece is three feet longer than twice the first piece.

Let the first piece = x

Let the second piece = 2x + 3

x + 2x + 3 = 30

Combine like terms

3x + 3 = 30

Subtract 3 from both sides

3x = 27

Divide 3 from both sides and we get:

x = 9

The first piece is 9 feet and now we need to find the second piece.

We can use the first piece to find the second piece.

Substitute 9 for x:

2(9) + 3

18 + 3 = 21

So the second piece is 21 feet.

21 + 9 = 30 feet

I want to fence in a square vegetable patch. The fencing for the east and west sides cost $7 per foot, and the fencing for the n
Bezzdna [24]

The total cost of the fencing is a function of the length of a side x (feet) is  10x + 14y.

<h3>How to find the perimeter?</h3>

The perimeter is made by adding the south, north, east, and west side.

Given that

The cost of fencing for the east and west sides is $7 per foot, and the cost of fencing for the north and south sides is only $5 per foot.

We have to find total cost of the fencing is a function of the length of a side x (feet).

The east and west fencing cost is $7/ft but the south and north fencing cost is $5/ft.

x = north and south fencing

y = the east and west sides, then you can get this equation.

Total cost= (south +north) × 5 + (east+ west) × 7

Total cost =(x + x) × 5 + (y+ y) × 7

Total cost = 5(2x) + 7(2y)

Total cost = 10x + 14y

Hence, the total cost of the fencing is a function of the length of a side x (feet) is 10x + 14y.
