Answer: 2x + 1
Step-by-step explanation:
The side opposite the 30o angle is 1/2 W. That is just a property of a 30 - 60 - 90 triangle. Use that fact to set up the pythagorean relationship.
w^2 = (1/2 w)^2 + (7 * sqrt(3)) ^2
w^2 = 1/4 w^2 + 49*3
w^2 = 1/4 w^2 + 147
3/4 w^2 = 147
w^2 = 147 * 4/3
w^2 = 49 * 4 = 196
w = sqrt (196)
w = 14
Answer:
The negative solution
-2
Step-by-step explanation:
Let the number be
Then 5 times the number is 5x.
14 less than the square of the number is
So our equation becomes
This implies that
We factor to get:
Answer:
7/6 or 1 1/6
Step-by-step explanation:
1/2+2/3 = 3/6 + 4/6 = 7/6
