A bedroom measures 9 feet long and 11 feet wide. A scale drawing is made using a scale factor of 112.
bazaltina [42]

Given the previous length of the bedroom and the current scale factor, the length of the bedroom in the current scale drawing is 1008ft.

<h3>What is the length of the bedroom in the scale drawing?</h3>

Scale factor is simply a measure for similar figures, who look the same but have different scales or measures.

To get new dimension;

New dimension = scale factor × current dimension

Given that;

  • Current length of the bedroom = 9ft
  • Current width of the bedroom = 11ft
  • Scale factor = 112
  • New length of the bedroom = ?

New dimension = scale factor × current dimension

New length of the bedroom = 112 × 9ft

New length of the bedroom = 1008ft

Therefore, given the previous length of the bedroom and the current scale factor, the length of the bedroom in the current scale drawing is 1008ft.

Y=3x+4 solve show work
stealth61 [152]

One solution:
x= 0
Y = 3x+ 4  =  4

Another solution:
x = -3
Y = 3x + 4  =  -5

Another solution:
x = -1
Y = 3x + 4  =  1

Another solution:
x = 1
Y = 3x + 4  =  7

Another solution:
x = 5
Y = 3x + 4  =  19

Another solution:
x = -10
Y = 3x + 4  =  -26

Another solution:
x = 10
Y = 3x + 4  =  34
