Answer:

X^2 - 2XY + Y^2

Step-by-step explanation:

GIVEN:

(x - y)^2

DISTRIBUTE:

(x-y)(x-y)

X * X = X^2

X * -Y= -XY

-Y * X = -XY

-Y * -Y = Y^2

COMBINE:

X^2 - 2XY + Y^2

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.
