X=2
Distribute 3 into parentheses. Then subtract 15 from both sides which gives you 3x=x+4.
Subtract x from both sides which gives you 2x=4. Divide by 2 on both sides thus giving you x=2.
Answer:
C (√10)/2
Step-by-step explanation:
Multiply numerator and denominator by √10. Then you have ...
... (5√10)/10 = (√10)/2
_____
Of course, you can always compare the given answers by using your calculator.
5/√10 ≈ 1.58114
The answer choices are ...
... A: 1.41421
... B: 2.23607
... C: 1.58114 . . . . matches the given expression in value
... D: 0.707107
_____
If you're familiar with the square roots of small integers, you can do this last exercise in your head once you have calculated 5/√10. That is, you can eliminate choices A, B, and D.
... √2 ≈ 1.414; √3 ≈ 1.732; √5 ≈ 2.236

Answer:2492
Step-by-step explanation:
4Log4(x+8)=4^2
Divide both sides by 4 we get
Log4(x+8)=4^2/4
Log4(x+8)=4
4(x+8)=10^4
4(x+8)=10000
Open brackets
4x+32=10000
Subtract 32 from both sides
4x+32-32=10000-32
4x=9968
Divide both sides by 4
4x/4=9968/4
X=2492
