The area of the trapezoid is 57.5 square inches.
If you draw out the description, you will see that your trapezoid can be divided into a rectangle that is 9 x 5 and an isosceles right triangle with a base of 5 and height of 5.
Just find the areas of both and add them together.
Rectangle:
5 x 9 = 45
Triangle:
0.5 x 5 x 5 = 12.5
45 + 12.5 = 57.5
Answer:
288
Step-by-step explanation:
The given statement is "nine times five less than twice x".
So, twice of x can be written as 2x and nine times five is 9*5.
Now 9*5 less 2x means we need to take out 9*5 from 2x.
Hence, this statement will be converted into an algebraic expression as follows:
2x-9*5
The answer is the temperature goes down 2.8° every hour and the expression is x=-11.2/4 because 4 is how many hours between 6pm and 10pm and its -11.2 because that was how much the temperature dropped from 6pm to 10pm
