Read explanation and apply it
Step-by-step explanation:
The vertex form of a quadratic equation is 
The general form of a quadratic equation is 
The factored form of a quadratic equation is 
The one which reveals the zeros of f(x) without needing to alter the equation is the factored form .
When f(x)=0, we have 
The values of x are 
and 
.
I hope this guides you to choose the correct answer.
Answer:
The value of x in the given figure is, 
Step-by-step explanation:
Complementary angle states that the two angles sum up to 90 degree.
From the given figure
and 
are complementary angles.
by definition of complementary angles;
Subtract from both sides we get;
Simplify:
therefore, the value of x in the given figure is,
Answer: look it up

Answer:
50
Step-by-step explanation:
If the first statement its true (At most 0 of the statements are true), there are not true statements in the paper. So, the first statement its false.
Now, if the first statement its false, this mean there must be at least 1 true statement in the paper.
Now, if the second statement its true ( at most 1 of the statements are true) this implies that the third statement its true (if "at most 1" its true, then "as most 2" must be true).
If any statement (besides the first) its true, then all the statement that follows it must be true.
The first non false statement, then, must be the statement made by the person 51: "At most 50 statements are true"
And the 49 statements that follows are true as well.
