Answer:
Axis of symmetry is
C) x = 1
Step-by-step explanation:
we are given equation as

we can use axis of symmetry formula
Let's assume we are given quadratic equation as

Axis of symmetry is

now, we can compare both equations
and we get

now, we can find axis of symmetry



Answer: The value of x is 3.
Step-by-step explanation:
Since we have given that
10,11, 12 and x
Average of above numbers = 9
As we know that
Average is given by

Hence, the value of x is 3.
U can see if it is a right triangle bu using the pythagorean theorem (or however it is spelled)
a^2 + b^2 = c^2....where a and b are the legs and c is the hypotenuse (the largest side)
so lets sub our numbers in and see if they equal
33^2 + 56^2 = 65^2
1089 + 3136 = 4225
4225 = 4225.......correct...so YES, this is a right triangle
