Aworker draws a 1/5 scale drawing of the top of a small air conditioning unit .the drawing is a rectangle with a length of 4 inches and width of 2 inches , what is the actual area of the top of the unit? how did you come to this conclusion?

you!

Area of the rectangle = L X W
Area of the rectangle = 4 X 2
Area of the rectangle = 8 inches
If the drawing is 1/5 of the actual air conditioning unit, then you multiply the reciprocal which is 5 times the area of the drawing. When you want to enlarge it has to be a whole number. When you want to reduce you multiply by a fraction.
So 8 inches X 5 = 40 inches is the actual area of the unit.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

Number nine is f(x)= 40x : ) hoped i ya
