I'm sorry but I don't see any terms, when I figure out how to put a photo in, I will help you with it.
Replace x with -1, and y = 9
Therefore, (x²y)/-7 becomes (-1² · 9)/-7
-1² is just 1, and 1 × 9 is just equal to 9, so your final answer is -9/7.
We know one side of the smaller rectangle, 6ft. Therefore the longer side is 78/6 ft = 13ft.
The ratio of small to large side is 6:10, so the larger rectangles other length is (13 / 6) * 10 ft = 21.666... ft.
Thus the area of the larger rectangle is 21.666... * 10 = 216.666... ft^2, and hence to the nearest whole number it is 217 ft^2
Divide 270 by 90 then the answer will be 3, so 1 candy bar is sold for $3
