A IS THE ANSWER
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The side lengths must satisfy the Pythagorean Theorem to be a right triangle. The formula is
where a is the smallest side, b is the medium side, and c is the largest side. Test each set of numbers.

This satisfies the theorem. Since this is a multiple choice question, only one solution is possible. A is the solution.
Answer:
A = 6 x 7
Step-by-step explanation:
To find the area of a parallelogram we use the equation of Area = base x height. In this case since the base is 6 and the height is 7, we plus in these numbers for the variables (b x h) to get the area.
Answer: 640
Step-by-step explanation:
The scale factor is 20/5=4, so the ratio of the areas is the square of this, or 16.
Thus, the area of ABCD is 40(16)=640.
2500-700 = 1800
1800/5 = 360
The annual depreciation of the camera is $360.
