Answer:
Number 1 and Number 4
Step-by-step explanation:
By factoring, you can figure out the roots (x = -2 or x = 2)...
1. x^2 - 4 = 0
--> (x + 2)(x - 2) = 0
--> x = -2, x = 2
2. x^2 + 4 = 0
--> factors weirdly, so I won't write it. You'd have to use the quadratic formula.
3. 3x^2 + 12 = 0
--> 3 (x^2 + 4) = 0
--> factors weirdly (same as above)
4. 4x^2 - 16 = 0
--> 4 (x^2 - 4) = 0
--> 4 (x+2) (x-2) = 0
--> x = -2, x = 2
5. 2 (x-2) 2 = 0
--> x = 2
Answer:
X times 3 + 4 =22
X=6
Step-by-step explanation:
22-4=18
18/3=6
I would have to say 32,4 but i would double check it
The volume for 1 a. is 79.50700. (You just multiply 4.3 by itself three times)
I don't know what the second one is though, sorry.
It is a false statement that the <span>bisector of a straight angle forms two acute angles. The correct option among the two options that are given in the question is the second option or the last option. I hope that this is the answer that you were looking for and and it has actually come to your desired help.</span>
