Answer:
Step-by-step explanation: 10/2 = 5
20^2= x^2 + 5^2
400=x^2+25
x^2=375
x= 19.4
6x² + 12x = 0
6x(x + 2) = 0
1. 6x = 0
⇒ x = 0
2. x+2 = 0
⇒ x = -2
Solutions are: {0, -2}
No. 4^2 + 8^2 or 16 + 64 is 80, and the hypotenuse, 12 (144) is not 80.
Quadrilateral the word that describe the equal share of 4 equal sides
