Answer:
280 ft squared
Step-by-step explanation:
To find the area of the nonshaded portion, we can find the area of the entire floor and then subtract the shaded area.
The total area is that of a rectangle: 30 * 15 = 450 ft squared.
Now, the shaded region is made up of a rectangle and a triangle.
- The rectangle has length 8 and width 10, so its area is 10 * 8 = 80 ft squared.
- The triangle has base 12 and height 15, so using the area of a triangle formula: (where b is the base and h is the height) = (12 * 15)/2 = 180/2 = 90 ft squared.
- The total shaded region is: 80 + 90 = 170 ft squared
Subtract 110 from 450: 450 - 170 = 280 ft squared.
Thus, the answer is 280 ft squared.

If 20% was taken off, that means that 35.96 is 80% of the original price.
35.96 =
Now, we just need to put it into fractions, cross multiply, and divide to find the original price.
35.96×100 = 3596
1×80 = 80
3596÷80 = 44.95
Now, to make sure, we multiply 44.95 by 20%,
44.95×0.20 = 8.99
Subtract that from 44.95
44.95-8.99 = 35.96
That is the sale price of the alarm clock.
This means that yes, the regular price of the mp3 alarm clock was
$44.95

I'm not sure if A B C D are answers, but I can say for sure that C is positive and A, B, and D are negative.
A:
Since there is only one -1, the expression is negative;
B:
Here as well, there is only one -1, so the expression is negative;
C:
The -1 cancels out;
D:
Here, you can't cancel the -1 out, so it remains negative;
Sorry for the delay, hope this helps :)
