For the equation,
y = 1/2(x+3)^2 -5
The vertice is (-3,-5). Therefore the axis of symmetry is X = -3.
To find the value of your expression, you could use the following steps;
First lets substitute the value of x in the equation;
7 + 2(-3 - 9) - (-3+ 2)
Next, simplify the parenthesis;
7 + 2(-12) - (-1)
7 - 24 + 1 = -16
So your final answer would be; -16
Well you could get 7 right
Answer:
x=6√3
Step-by-step explanation:
In 30-60-90 triangles, if the hypotenuse is <em>x</em>, the longest leg is
, and the shortest leg is
.
If the longest leg is 6, then 
Multiply by 2,

If x=12,


So, the shortest leg is 6√3.
