Answer:
seven times the difference of a number b, and two
Step-by-step explanation:
hope this helps
S=2(4x+2x)+4x^2=4x^2+12x
4x^2+12x=7
4x^2+12x-7=0
D=12^2-4x4x(-7)=256
X1=(-12-16)/(2x4)=-3.5 impossible
X2=(-12+16)/(2x4)=0.5

Assume that pi is approx. 3.14. Then 86.92 = approx. 27 2/3 times pi, or
86.92 is approx. equal to 83pi/3.
True, because a independent value can have as much dependent values as it wants.
Answer:
The area of the bedroom actually is 453.75 sq ft.
Step-by-step explanation:
Given that,
A blueprint shows the master bedroom to be 5 inches long and 3 inches wide.
The scale on blueprint is 2 inches : 11 feet.
It means 2 inches = 11 feet.
Then,
1 inches feet = 5.5 feet.
So,
The length of the bedroom is 5 inches = (5×5.5) feet=27.5 feet
The wide of the bedroom is 3 inches = (3×5.5) feet= 16.5 feet
The area of the bedroom actually is = length × wide
=(27.5×16.5) square ft
=453.75 square ft
