126cm. This is the answer if the area is not given. A triangle layed flat out is 180 if one length is 45 and another is 9 you add the sides and subtract the number from 180 which is 126.

5A + 7 = 3A + 7 + 2A
We need to solve for A.

3A + 7 + 2A = 3A + 2A + 7 = 5A + 7 (We can add 3A and 2A because it's the same variable, so we add the coefficients)

5A + 7 = 3A + 7 + 2A
5A + 7 = 5A + 7

5A + 7 is always equal to 5A + 7 because it's the same equation. So the equation got infinitely many solutions.

Answer:

The answer is "Choice B".

Step-by-step explanation:

Please find the complete question in the attached file.

In this question, in all choices, the choice (B) is Correct because in the declaration of the statement Only when the process has had at least another answer could a candidate solution for more than just a linear model explicitly uses a parametric description that's why the given statement is true.
