Answer:

9 ft

Step-by-step explanation:

So let's assume the shape is rectangular.

The perimeter of the rectangle with dimensions l and w is: 2w+2l.

We are given 48 feet of wood so we want 2w+2l=48.

Manny wants l to be 15 so insert this into equation: 2w+2(15)=48.

Now we need to solve

2w+2(15)=48

Multiplying 2 and 15:

2w+30=48

Subtract 30 on both sides:

2w     =18

Divide both sides by 2:

 w     =9

We want the width to be 9 ft.

Answer:

9 feet

Step-by-step explanation:

15+15= 30. 48 - 30 = 18. 18/2= 9. If 48 is the perimeter than it should have 15 as  the length and 9 as the width.

Mr. Johnson currently has a square garden. He wants to redesign his garden and make it into a rectangle with a length that is 5
AlekseyPX

Answer:

Width of the rectangle = 10 feet

Length of the rectangle = 25 feet

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

Let

Width of the rectangle = x feet

Length of the rectangle = 3x - 5 feet

Perimeter of the rectangle = 70 feet

Perimeter of a rectangle = 2(length + width)

70 = 2{x + (3x - 5)}

70 = 2{x + 3x - 5}

70 = 2(4x - 5)

70 = 8x - 10

70 + 10 = 8x

80 = 8x

Divide both sides by 8

x = 80 / 8

= 10

Width of the rectangle = 10 feet

Length of the rectangle = 3(10) - 5

= 30 - 5

= 25 feet

The vertices of a triangle are p(3,7) Q(7,-6) R(-8,7). Name the vertices of the image reflected across the x axis
pantera1 [17]

Answer:

<em>P'(3,-7) Q'(7,6) R'(-8,-7).</em>

Step-by-step explanation:

<u>Reflection across the x-axis</u>

Given a point P(x,y), its reflection across the x-axis will map to point P'(x,-y), i.e., the y-coordinate gets inverted.

We are given the vertices of a triangle P(3,7) Q(7,-6) R(-8,7). The vertices of the image reflected across the x-axis are:

P'(3,-7) Q'(7,6) R'(-8,-7).

The new triangle has vertices P'Q'R'.
