Using Pythagoras:-
x^2 = 6^2 + (sqrt18)^2
= 36 + 18 = 54
x = sqrt54 = 3 sqrt6
Answer:
141°
Step-by-step explanation:
39*2 = 78
360 - 78 = 282
282/2 = 141
I gotchu !! just give me a moment to write it out
Consider expression
First, you can factor it:

Since x is integer number, then you can see that x-1 is previous integer number (x-1 is 1 unit smaller than x).
Therefore, x-1 and x are two consecutive integers. When you have two consecutive integers, one of them is always even and one is always odd. Multiplying even integer number by odd integer number you always get even integer number.
Thus,
is always even.
Answer:
7
Step-by-step explanation:
So basically first distribute the -5 to the stuff in the parenthesis and then solve.
Hope I helped!! :)
