Answer:
Step-by-step explanation:
In the equation:
x's can be simplified and y's can be simplified!
Always remember that for exponents, you subtract the powers when dividing

Answer:
58 square feet
Step-by-step explanation:
The room is already broken down into two smaller rectangles.
The smaller of the two measures 4 ft by 2 ft. , so substitute 4 for
and 2 for
.
(smaller rectangle)
, or
.
(smaller rectangle)
The larger measures 10 ft by 5 ft, so using the same method, multiply times
.
(larger rectangle)
, or
.
(larger rectangle)
Add the two rectangles' areas together to find the total area of the room.
8 + 50 = 58
