3. Mr. Jones is going to build a garden in back of the restaurant to have

Svetach [21]

Answer: The amount of fencing needed can be expressed as 6x + 6 ft and, the cost of fencing can be expressed as Cost = 18x + 18

Step-by-step explanation: The dimensions of the rectangular garden are given as

Length = 2x + 3

Width = x

The amount of fencing that he would need is simply the total measurement all around the rectangular garden, that is, the perimeter. The perimeter of a rectangle is given as follows;

Perimeter = 2(L + W)

With the dimensions already provided we can now substitute for the values

Perimeter = 2(2x + 3 + x)

Perimeter = 2(3x + 3)

Perimeter = 6x + 6

Therefore the amount of fencing needed can be written out as,

6x + 6 ft

If however, fencing costs $3 per foot, then the cost of the entire fencing can be expressed as

Cost = 3(6x + 6)

Cost = 18x + 18

A)<br> 2x + y - 12 = 0<br> x + y + 3 = 0

AVprozaik [17]

Answer:

x=15 and y= -18

Step-by-step explanation:

$2x + y - 12 = 0$ Equation 1

$x + y + 3 = 0$ Equation 2

From two given equations, we can find the value of both x and y by finding the value of one variable from any one of the two equations in terms of other variable and putting it to other equation.

Solving equation 1

Finding 'y' in terms of 'x' $2x+y=12\\y=12-2x$ Equation 3
