Nick was thinking of a number. Nick adds 9 4 to the number, then doubles the result to get an answer of 16.8. Form an equation with from the information

4.

step-by-step explanation:

it have the same area.brainliest

what graph

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
