Answer:
1. x=±4
2. t=±9
3. r=±10
4. x=±12
5. s=±5
Step-by-step explanation:
1. x^2 = 16
Taking square root on both sides
x=±4
2. t^2=81
Taking square root on both sides
t=±9
3. r^2-100=0
r=±10
4. x²-144=0
x²=144
Taking square root on both sides
x=±12
5. 2s²=50
s=±5 ..
" = 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
