Question

Please help with this question

Answer 1

`a=250, \ b=10`

Explanation:

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

Answer 2

Hi there!

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

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

Let's solve A:

`a = (5(10)^2)/(2)`

`a = (5 * 100)/(2)`

`a = (500)/(2)`

`a = 250`

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

Let's solve B:

`b = (2(10)^2(x(10)-5))/(10(10))`

`b = (2(100)(5))/(100)`

`b = (200 * 5)/(100)`

`b = (1000)/(100)`

`b = 10`

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