A rectangle has a width of 8 units and a length of 10 units. What is the length of the
diagonal of this rectangle

12.8 units

Step-by-step explanation:

Adding a diagonal makes it into 2 of the same right-angled triangles.

In right angled triangles, you can use Pythagoras' therorem which says that a^2+b^2=c^2 where a and b are the shorter sides and c is the diagonal.

This means that 8^2+10^2=diagonal^2=64+100=164

The diagonal is then the square root of 164 which equals 12.806248...

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
