Answer:

a=250, \ b=10

Step-by-step explanation:

a=\frac{5\cdot10^2}2=\frac{5\cdot100}2=\frac{500}2=250\\ b=\frac{2\cdot10^2\cdot(10-5)}{10\cdot10}=\frac{2\cdot100\cdot5}{100}=\frac{1000}{100}=10

Hi there!

Find the value of a and b when x = 10.

-------------------------------------------------------

Let's solve A:

a = \frac{5(10)^2}{2}

a = \frac{5 * 100}{2}

a = \frac{500}{2}

a = 250

-------------------------------------------------------

Let's solve B:

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

b = \frac{2(100)(5)}{100}

b = \frac{200 * 5}{100}

b = \frac{1000}{100}

b = 10

-------------------------------------------------------

Hope This Helps :)
