Answer:
The length of BC is 17
Step-by-step explanation:
When we construct a triangle with the data, we will end up a isosceles triangle.
In a isosceles triangle , we know that tow angles and two sides are equal
The questions states that
![\angle b = \angle c](https://tex.z-dn.net/?f=%5Cangle%20b%20%3D%20%5Cangle%20c)
Then sides AC and AB are also equal
On equation their values
2X - 8 = X+9
2X = X + 9 +8
2X = X + 17
2X - X = 17
X = 17
The length of BC = X = 17
Answer:
2*26=52
Step-by-step explanation: you can just use a calculator to find 2*26 and you will find that the answer to your question is 52.
<span>Difference of squares method is a method that is used to evaluate the difference between two perfect squares.
For example, given an algebraic expression in the form:
can be factored as follows:
![(x-y)(x+y)](https://tex.z-dn.net/?f=%28x-y%29%28x%2By%29)
From the given expressions, the only expression containing two perfect squares with the minus sign in the middle is the expression in option A.
i.e.
![25x^2-64y^2](https://tex.z-dn.net/?f=25x%5E2-64y%5E2)
which can be factored as follows:
![(5x-8y)(5x+8y)](https://tex.z-dn.net/?f=%285x-8y%29%285x%2B8y%29)
