Twenty eight is composite
28 can be divided by one, by itself and at least by 2 and 7
Answer:
5y=9
Step-by-step explanation:
In a right angle, the sum of the squares of the two shorter sides is equal to the square of the longest side.
Here, the longest side is 25, the shorter sides are x and x+5.

The length of a side must be a positive number, so x=15.
The answer is C.
You have 2x^2 + 9x -9 and 3x^2 -2x +14
To find total area add the two polynomials together by combining the like terms.
2x^2 + 3x^2 = 5x^2
9x + -2x = 9x-2x = 7x
-9 + 14 = 5
Total area = 5x^2 + 7x + 5
