Your answer is -4.23 degrees fahrenheit.
To get that answer you must take you starting temperature, 9.17, and your decreased amount of temperature, 13.4, and subtract them.
So, you have 9.17 - 13.4 = -4.23
You can not reverse the numbers or it will give you the wrong answer.
Answer:
180 ft2
Step-by-step explanation:
First solve for the area of the trapzeoid using formula:
A= a+b/2xh
10+18x6/2
A= 84 ft2
Then solve for the rectangles B and C:
12x4= 48
48x2 (because theres two rectangles) which equals 96
Combine the two to get the total area:
96+84= 180
