True because a triangle must have 3 angles that add up to 180 degrees and, since a right angle is 90 degrees, it cannot have 2 right angles
Answer:
With this form, we can tell that the x intercepts are x=6 and x=-2. So the x coordinate of the vertex is 2

Im in 7th grade and I need some help on a math problem. can I post it?
Answer
its the third one.
Step-by-step explanation:
Answer:
(X+2) (X-2) . This is the final answer
Step-by-step explanation:
Solving f(x) = x^2 - 4
A^2 - B^2 is a special case where the original equation before it was foiled is
(A + B) (A - B) because the middle terms will cancel out when foiled.
This means that the equation can be written as
(X + 2)(X - 2) = 0
Each of these you will then set equal to 0 and then solve
X + 2 = 0, X - 2 = 0
X = -2, 2
I hope this helps you! let me now if its right ok <3 :)
