Answer: a=2 b= 11/6 or 1 5/6
Step-by-step explanation:
Answer:
B. -3
Step-by-step explanation:
Answer:
Step-by-step explanation:
To simplify 7/√x, we need to rationalize:
When we multiply the 2, we should get our answer:
Answer is 10(2k+5)
-----------------------------------
Work Shown:
20k+50 = 10*2k + 10*5
20k+50 = 10(2k+5)
Note how we can distribute the 10 back in to check our work
10(2k+5) = 10(2k)+10(5) = 20k+50
so that confirms we have the right answer
Another thing to notice is that 10 is the largest factor that we can pull out of 20k and 50. The value 10 is the GCF (greatest common factor) of 20 and 50.
Step 1: Factor left side of equation.
(3x+2)(2x+1)=0
Step 2: Set factors equal to 0.
3x+2=0 or 2x+1=0
x=−23 or x=−12
Answer:
x=−23 or x=−12
