i think G sorry if its wrong
Step-by-step explanation:
Answer:
identity property of multiplication
The first one is neither
No. 2 is perpendicular ( because slope = -1/ slope of the other)
No 3 is parallel (both have slope of 3/4)
No 4 is perpendicular.
" = inches
' = feet
the scale is 1:30
3" * 30" = 90"
4" * 30" = 120"
the room is 90" by 120"
90" / 12" = 7.5'
120" / 12" = 10'
the room is 7.5' by 10'
7.5' * 10' = 75' ^2
^ = exponential sign (10^2) means 10 to the second power.
The area of the room is 75' ^2
