what is the numbers to choose from
Answer:
x=3
Step-by-step explanation:
log₂(3x-1)=3
(3x-1)=2³
3x-1=8
3x=8+1
3x=9
x=9/3
x=3
Answer:
x = 0 or x = 5/2
Step-by-step explanation:
Solve for x over the real numbers:
x^2 sqrt(2 x - 5) = 0
Split into two equations:
x^2 = 0 or sqrt(2 x - 5) = 0
Take the square root of both sides:
x = 0 or sqrt(2 x - 5) = 0
Square both sides:
x = 0 or 2 x - 5 = 0
Add 5 to both sides:
x = 0 or 2 x = 5
Divide both sides by 2:
Answer: x = 0 or x = 5/2
I first would rearrange the problem
-220x^2 + 20x + 600x
Simplify
-220x^2 + 620x
Find the GCF of the two values
20x(11x + 13)
Hope this helps!
