Y=12, and X=18, it’s a 30 60 90 triangle
Answer:
99
Step-by-step explanation:
Through some clever algebra, we can combine our first two equations using the fact that
We have the a² and the b² in the equation 
, and we <em>almost </em>have a 2ab in the equation 
. To get that 2ab, we can simply double both sides of the first equation to get 
. From there, we'll add the first two equations together, giving us the summed equation
And since , we can equivalently say that
It’s c i know bc i had the question
Answer:
660
Step-by-step explanation:
66 hundreds is 6600 so divided by 10 it's 660
Answer:
6c^2(-40 + 5c^3 + 3c^2)
Step-by-step explanation:
These three terms have the common factor c^2. Thus:
-240c^2+ 30c^5+ 18c^4 = c^2(-240+ 30c^3+ 18c^2).
Recognizing that 6 is common to all three terms inside the parentheses, we get:
6c^2(-40 + 5c^3 + 3c^2) This is as far as factoring of this expression can be taken.
