Answer:
180 square feet
Step-by-step explanation:
We know that the rectangular drawing has:
- 5 inches long (L)
- 4 inches wide (W)
And we also know that:
<em>1 inch = 3 feet</em>
We will find how many feet long and wide is the actual room, by multiplying:
Long: 5 inches * 3 feet/inch = 15 feet
Wide: 4 inches * 3 feet/ inch = 12 feet
Now we want to know the area of the rectangle, and the area of the rectangle is:
<em>A = L*W</em>
<em>A = 15 feet * 12 feet</em>
A = 180 square feet
Answer:
x=-5
Step-by-step explanation:
-3x+25=40. You want to isolate x so you have to subtract 25 from both sides. -3x=15. We then want x to be isolated so we have to divide both sides by -3 to make x by itself. x=-5. Therefore, x=-5.

Answer:
729
Step-by-step explanation:
I have not done this in some time so the terms may be a bit unconventional, but they work. The key to this is multiplying by -3.
1*(-3) = -3
-3*(-3) = 9
And so on.
1, -3, 9, -27, 81, -243, 729
