3x^2 = 147
divide both sides by 3
x^2 = 49
x^2 -49 = 0
(x-7)(x+7) =0
so,, x = 7 , -7
the answer is B
Answer:
Hope this helps
Step-by-step explanation:
Positive Integer factors of 330 = 2, 3, 6, 5, 30, 11, 330 divided by 2, 3, 5, 11, gives no remainder. They are integers and prime numbers of 330, they are also called composite number.
-3 is the slope.
Explanation:
We would use the slope formula for this.
Slope formula: y2-y1/x2-x1
1-(-8)/-1-2
9/-3
-3
3r + 2rt = 18
r is the common factor
r(3 + 2t) = 18
r= 18/ 3 + 2t
r= 6 + 9t
