The common factor of 5x2 is y5x
(x + 2)(x - 4)
= x^2 + 2x - 4x - 8
= x^2 - 2x - 8
a mathematical operation, such as addition or multiplication, performed on two elements of a set to derive a third element.
Answer:
Option D
Step-by-step explanation:
The pythagorean equation states that a^2+b^2=c^2, with c^2 being the hypotenuse and a^2 and b^2 being the legs. if you input the values into the formula you get 2^2 + 6^2 = 40. 40 does not square evenly so you have to convert √40 into simplest radical form. when you do this you get 2√10
