Because 6 * 8 + ( - 2 )* 24 = 48 - 48 = 0 , the vectora u and v are orthogonal ;
Two vectors are orthogonal if their dot product is zero.<span />
It is 30 because u r dividing by 2 every time
33 + 6x = 3(-1 + 5x)
33 + 6x = -3 + 15x
33 = -3 + 9x
36 = 9x
4 = x
Answer:
x = 4
Hope this helps.

Pythagorean's Theorem
A and b are both side lengths, c is the hypotenuse.
7^2 + 5^2 = 74
sqrt(74) is the answer for 1.
30^2 - 5^2 = 875
Simplify the radical. sqrt(875) --> 5sqrt(35). The answer for three.
There's a rule in geometry that says a diagonal of a square is the same length as taking a side length times the square root of two. There's your answer for two.
