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:
C. 2
Step-by-step explanation:
The greatest common factor (GCF) is the highest factor of two numbers...
2 (2) = 4
1 (2) = 2
Answer:
B. 8x + 56
Step-by-step explanation:
Answer:
<h2><u>
369</u></h2>
Step-by-step explanation:
Since the equation of the line is y = 1/3x , or y = 0.33333333x , you multiply y, seltzer, by 3. You do this because x is 3 times the value of y.
Graphing the equation can be seen below
