C. 9 square roots of 2
To answer this question, it's super important that you understand the ratio of sides for special triangles. This triangle in particular, a 45-45-90 triangle, has a ratio between the legs and hypotenuse of 1:1:
Since we are given the value of the hypotenuse, we know that the value of the two sides multiplied by 
will be 18. Knowing this, we can write out an equation:
u* = 18
u = 
<u>Multiply both sides by </u><u> in order to get rid of the root in the denominator:</u>
u = 
u = 
u = 9
If you'd like me to explain how I got to the answer any further, just ask!

Answer:
A - 4/13ths is a larger number
B- 3/10ths is a ratoinal mumner
Step-by-step explanation:
if x is equal to - 1
Then
2x² + 5x + 6
= 2* ( -1)² + 5 * (- 1) + 6
= 2 - 5 + 6
= 8 - 5
= 3
Hope it will help :)❤
Answer:
Step-by-step explanation:
Start with our equation:
s=2(lw+wh+hl)
Plug in our values for l, w, and h:
s=2(12*9+9*2+2*12)
Simplify:
s=300
Do the area of the circle as a whole minus (72/360 x radius^2) and then minus the other grey area.
