PEMDAS: distribute the negative to (-2-5x) so it becomes (2+5x)+(-2)=18
Add 2 to both sides: 2+5x=20
Subtract 2: 5x=18
Divide 5: x= 18/5
Answer:
x = 4
Step-by-step explanation:
The ratio of the side opposite the large filled dot to the hypotenuse is ...
16/20 = x/5
(4/5)(5) = x = 4 . . . . multiply by 5
The value of x is 4.

The angle marks tell us the triangles are similar.
4 i
I is the square root of negative one
The triangle shown is a right triangle shown by the little square inside of it.
Area of a triangle is 1/2 x height x base
Rotating the shown triangle so the square is at a bottom corner the height is 6 and the base is 6
Area = 1/2 x 6 x 6 = 18 square cm
