We have this equation:

P=2L+2W

So, we need to solve this equation for L. Then we sum -2W in each member of the equation, like this:

P-2W=2L+2W-2W
P-2W=2L

Then, dividing the equation by 2:

\frac{P-2W}{2}=L

Finally, let's order this equation:


L=\frac{P-2W}{2}

So you have to simplify



(9 x 10 x 18) 2 + (5 x 10 x 18) (-7) + (5 x 9 x 18)

(-11) + (5 x 9 x 10)

5 x 9 x 10 x 18

1620 x 2 + 900 (-7) + 810(-11) + 450 x 5
x 5 x 9 x 10 x 18

The answer would be -6/5

On a blueprint lets say that every 1/4 inch is equal to 1 foot in real life.
Murrr4er [49]

Answer:

15 ft

Step-by-step explanation:

If every 1/4 of an inch is a foot, than every inch is 4 feet.

1 inch = 4ft

3 inches = 12ft

1/4 + 1/4 + 1/4 = 3/4

3/4=3 ft

12+3=15ft
