Step-by-step explanation:

Step 1: Define

$a=\frac{5x^2}{2}$

$b=\frac{2x^2(x-5)}{10x}$

x = 10

Step 2: Evaluate

a

1. Substitute in x:                    $a=\frac{5(10)^2}{2}$
2. Exponents:                          $a=\frac{5(100)}{2}$
3. Multiply:                               $a=\frac{500}{2}$
4. Divide:                                 $a=250$

b

1. Substitute in x:                    $b=\frac{2(10)^2(10-5)}{10(10)}$
2. Exponents:                          $b=\frac{2(100)(10-5)}{10(10)}$
3. Subtract:                              $b=\frac{2(100)(5)}{10(10)}$
4. Multiply:                               $b=\frac{1000}{100}$
5. Divide:                                 $b=10$

Answer 2

I think A is 250 and B is 10
