Answer:
b. 0
Step-by-step explanation:
We have been given an equation . We are asked to find the number of solutions for our given equation.
Let us solve our given equation. Using distributive property , we will get:
Adding 3x on both sides of our equation, we will get:
Since both sides of our given equation are not equal, therefore, our given equation has no solution and option 'b' is the correct choice.

Answer:
40 (cm)
Step-by-step explanation:
0. make up a new picture with additional elements (radius of the inscribed circle, it's 'x'; and some elements as shown in the attached picture);
1. the formula of the required perimeter is P=a+b+c, where c- hypotenuse.
2. apply the Pythagorean theorem: a²+b²=c², where c - hypotenuse, then calculate value of 'x' (attention! x>0, the length is positive value !)
3. substitute 'x' into the formula of the required perimeter. The result is 40.
PS. All the details are in the attached picture, answer is marked with red colour.
