Answer:
Y=-3x+7
Step-by-step explanation:
it hit the y axis at 7
And it is going down by 3
2x^2 +13x + 6 =
2x^2 + 12x + x + 6 =
2x(x + 6) + 1(x + 6) =
(2x + 1)(x+6)
Alright, lets get started.
Please refer the diagram, I have attached.
∠ABC is given as y.
So, the ∠EBC will be 180 - ∠ABC.
∠EBC = 180 - y
As given in question, BO is the bisector of ∠EBC, it means ∠OBC will be half of the ∠EBC.
∠OBC = of ∠EBC
∠OBC = (180 - y)
∠OBC =
Similarly,
the ∠DCB will be 180 - ∠ACB
∠DCB = 180 - z
As given in question, CO is the bisector of ∠DCB, it means ∠OCB will be half of the ∠DCB.
∠OCB = of ∠DCB
∠OCB = (180 - z)
∠OCB =
In triangle OBC, the sum of the angles of the triangle will be 180.
∠BOC + + = 180
∠BOC +
∠BOC = =
As per upper triangle ABC,
or
Putting this value in value of ∠BOC
∠BOC =
∠BOC =
∠BOC = 90 - : Hence proved
Hope it will help :)
Answer:
27 by 27
Step-by-step explanation:
Let the sides be x and y. The problem is essentially asking:
Given 2(x+y)=108, maximize xy.
We know that x+y=54. By the Arithmetic Mean - Geometric Mean inequality, we can see that . Substituting in x+y=54, we get , meaning that . Equality will only be obtained when x=y (in this case it will generate the maximum for xy), so setting x = y, we can see that x = y = 27. Hence, 27 is the answer you are looking for.
