The answer should be 4.

First, simplify \frac{8}{2} to 4. Your problem should look like: 4 x 1. 
Second, multiply. 4 x 1 = 4 so that is your answer.

Also, 
to start the equation up, make sure to add in the numbers in replace for the letters. Your problem to start with should look like: \frac{8}{2(1)}.

Find the distance between (-1,-2) and (8,9)
Rom4ik [11]

Answer:

\sqrt{202} units or 14.2 units (rounded to the nearest tenth)

Step-by-step explanation:

To find the distance between a pair of two points, use the distance formula  d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}. Substitute the x and y values of (-1,-2) and (8,9) into the formula and simplify:

d = \sqrt{(-1-8)^2+(-2-9)^2} \\d = \sqrt{(-9)^2+(-11)^2} \\d = \sqrt{81+121} \\d= \sqrt{202}  

So, as an exact answer, the distance is \sqrt{202} units.

(To find the decimal approximate of that answer, enter it into a calculator. This would make the decimal approximate 14.2 units, when rounded to the nearest tenth.)
