Answer:
The correct answer is 3 × 5 + 3 × 7 + 6 × 7 = 78 square feet.
Step-by-step explanation:
Measures of Chad's window is 36 inches by 60 inches = 3 feet by 5 feet.
Area of the window is 15 square feet.
Measures of Chad's door is 36 inches by 84 inches = 3 feet by 7 feet.
Area of the door is 21 square feet.
Measures of Chad's closet is 72 inches by 84 inches = 6 feet by 7 feet.
Area of the closet is 42 square feet.
Equation to show the total area of window, door and closet is 15 + 21 + 42 = 78 square feet.

Answer:
12 a. 4605 feet 12 b. 1,459,063 square feet
Step-by-step explanation:
For the perimeter, we simply add the lengths of each of the 5 sides together (or multiply 5 times one side length).
P = 5(921)
P = 4605 feet
For the area, we will use composition...add the area of the triangle to the area of the trapezoid.
For the area of the triangle, the formula is
.
Filling in our values gives us
and
A = 403,045 square feet.
Now for the trapezoid. The formula for a trapezoid is
where the b's represent the bases and the h represents the height. Filling in our values gives us
Work inside the parenthesis first:
and
A = 1,056,018
Now we add those together to get that area of the Pentagon is 1,459,063 square feet
Answer:
O 30, 36, 42
Step-by-step explanation:
6 = 1 × 6, 12 = 2 × 6, 18 = 3 × 6, 24 = 4 × 6, ? = 5 × 6 = <u>30</u>, ? = 6 × 6 = <u>36</u>, ? = 7 × 6 = <u>42</u>
Answer:
The answer is four months
Step-by-step explanation:
You have a starting cost of $50 with a $20 fee every month
OR
You have a starting cost of $30 with a $25 fee every month
Start: $50 ($20 per month)
M1 = $70, M2 = $90, M3 = $110, M4 = $130
Start: $30 ($25 per month)
M1 = $55, M2 = $80, M3 = $105, M4 = $130
In conclusion, the prices of the two will match at Month 4
