linda is building a rectangular playhouse. the width is x feet. the length is x + 3 the distance around the base of the playhouse is 36 feet. is 8 the value of x? explain

Answers

Answer 1
Answer:

The value of x is 7.5, not 8. Hence, 8 is not the correct value of x.

What is the value of x?

The perimeter of a rectangle is expressed as:

Perimeter = 2( length + width )

Given that:
The width of the rectangular playhouse = x feet

The length = x + 3

Perimeter = 36 feet

To determine whether 8 is the value of x, we can set up an equation using the formula for the perimeter of a rectangle.

Perimeter = 2( length + width )

Plug in the given values:

36 = 2( (x+3) + x )

Solve for x:

36 = 2( 2x + 3 )

36 = 4x + 6

4x = 36 - 6

4x = 30

x = 30/4

x = 7.5

Based on the calculation, the value of x is 7.5, not 8.

What is m∠CDJ? Im not sure what it is

Answers

4x+3x-8=90\n7x=98\nx=14\n\n\angle CDJ=3\cdot14-8=34^(\circ)

The 'x' and 'y' axes are perpendicular.
So angle ADJ is 90 degrees.

So (4x) + (3x-8) = 90 degrees.

Solve that and you'll know what 'x' is.

Then angle CDJ is just (3x-8).

I'm sure you can handle it from here.

On a scale drawing of a workshop, 1 inch equals 4 feet. The actual dimensions of the workshop are 40 feet by 60 feet. What are the dimensions of the workshop in the scale drawing?

Answers

On a scale drawing 1 inch equals to 4 feet. 40 by 60 feet is the real one. If you want to find how many inches it is actually you need to divide 40 and 60 by 4. 40 divided by 4 is 10.  60 divided by 4 is 15. The real dimension is 10 by 15.
