Step-by-step explanation:
Answer:
1 hr 20 min.
Step-by-step explanation:
2x^2-12x+18=0
Factor out GCF
2(x^2-6x+9)
Factor trinomial
(x-3)(x-3)
Proof
-3-3=-6
-3^2=9
Zeros
x-3=0
x=3
Final answer: B
A) 2√3
B)3√3
C)5√2
Because radicals multiply like rational numbers
Answer: 30
Step-by-step explanation:
Simple formula is
LCM*GCF=PRODUCT OF 2 NUMBERS
120 * 10 = 40 * x
1200 = 40x
x = 1200/40
x = 30
