To find how much paint would I need to buy to paint the walls of all three bedrooms, calculate the area of all three bedrooms
<em>Master Bedroom</em>
The area is equal to

<em>2 Bedroom</em>
The area is equal to

<em>3 Bedroom</em>
The area is equal to

The total area is equal to
A=A1+A2+A3

Approximate one gallon of paint covers 250 square feet
so

Answer: y=-4x-31
Step-by-step explanation:
To find a ling that is parallel to the given line and passes through the given point, we need to use the given point. We know that the slope MUST stay the same because parallel lines NEVER touch. All we have to do is plug in the point and find the y-intercept.
-7=-4(-6)+b [multiply]
-7=24+b [subtract both sides by 24]
b=-31
Now, we know that y=-4x-31 is the equation.
The second equation would be correct if x = 4.
6x / 8 = 3 6 x 4 = 24 and 24 / 8 = 3
Answer:
2500 ft²
Step-by-step explanation:
The missing area at lower right in the diagram has dimensions...
(4-2 1/4) by (3 - 1 3/4) by (1 1/4)
Then area of that "Missing" space is (1.75)(1.25)= 2.1875 . . . . square inches. The area of the enclosing rectangle is ... (4 in) (3 in) = 12 square inches the area in the diagram representing the store is... 12 in² -2.1875 in² = 9.8125 in²
_
Each square inch on that diagram represents an actual area of (1 in)×(1 in) → (16 ft)×(16 ft) = 265 ft²
Then the actual store area is....
9.8125(256 ft²) = 2512 ft²
Rounded to the nearest 50 ft², this is 2500 ft².
