Answer:

The amount of fencing is 6x + 6

And the cost = 18x + 18

Step-by-step explanation:

Here,we were provided with the dimensions of the rectangular garden.

They are:

Length = 2x + 3

Width = x

The amount of fencing that he would be needed is the total measurement all around the rectangular garden, and in this case, the perimeter. We all know tat the perimeter of a rectangle is

Perimeter = (L + W) × 2

With the parameters already outlined, we can now substitute for the values

Perimeter = (2x + 3 + x) × 2

= (3x + 3) × 2

= 6x + 6

So therefore, the amount of fencing needed can be written out as,

6x + 6 ft

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

C = 3(6x + 6) c here means the cost

C = 18x + 18

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 triangle has vertices at B(-3,0), C(2, -1), D(-1,2). Which series of transformations would produce an image with vertices B"(4

Alik [6]

Answer:

(b) (x, y) ⇒ (-x, y); (x, y) ⇒ (x + 1, y + 1)

Step-by-step explanation:

A graph shows the image is consistent with reflection over the y-axis

(x, y) ⇒ (-x, y)

and translation right 1, up 1

(x, y) ⇒ (x +1, y +1)

These transformations are listed in the second choice.

In the attachment, the original image is blue, the reflected image is purple, and the final translated image is red.

What is the value of the x variable in the solution to the following system of equations? 4x − 3y = 3 5x − 4y = 3

andrew-mc [135]

Solve 4x − 3y = 3 and 5x − 4y = 3

Step 1: Solve for x in 4x-3y=3:
4x-3y=3
4x-3y+3y=3+3y [Add 3y to both sides]
4x=3y+3
 $\frac{4x}{4} = \frac{3x+3}{4}$ [Divide both sides by 4]
x= $\frac{3}{4}y+ \frac{3}{4}$

Step 2: Substitute $\frac{3}{4}y+ \frac{3}{4}$ for x in 5x-4y=3
5x-4y=3
5( $\frac{3}{4}y+ \frac{3}{4}$ )-4y=3
 $\frac{-1}{4}y+ \frac{15}{4} =3$
$\frac{-1}{4}y+ \frac{15}{4} - \frac{15}{4} =3- \frac{15}{4}$ [Subtract $\frac{15}{4}$ to both sides]
$\frac{-1}{4}y= \frac{-3}{4}$
$\frac{ \frac{-1}{4}y}{ \frac{-1}{4} }= \frac{\frac{-3}{4} }{ \frac{-1}{4}}$ [Divide both sides by $\frac{-1}{4}$ ]
y = 3

Step 3: Substitute 3 for y in x = $\frac{3}{4}y+ \frac{3}{4}$
$\frac{3}{4}y+ \frac{3}{4}$
$\frac{3}{4}(3)+ \frac{3}{4}$
x = 3
