Please help with this question

Answer:
[tex]a=250, \ b=10[/tex]
Step-by-step explanation:
[tex]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[/tex]
Hi there!
Find the value of a and b when x = 10.
-------------------------------------------------------
Let's solve A:
[tex]a = \frac{5(10)^2}{2}[/tex]
[tex]a = \frac{5 * 100}{2}[/tex]
[tex]a = \frac{500}{2}[/tex]
[tex]a = 250[/tex]
-------------------------------------------------------
Let's solve B:
[tex]b = \frac{2(10)^2(x(10)-5)}{10(10)}[/tex]
[tex]b = \frac{2(100)(5)}{100}[/tex]
[tex]b = \frac{200 * 5}{100}[/tex]
[tex]b = \frac{1000}{100}[/tex]
[tex]b = 10[/tex]
