Step-by-step explanation:
step 1. what is the question? probably solve for x. okay.
step 2. 4^(2x) + 1 = 4
step 3. 4^(2x) = 3 subtract 1 from each side
step 4. ln4^(2x) = ln3 take on of each side
step 5. 2xln4 = ln3 definition of logs
step 6. 2x = ln3/ln4 divide both sides by ln4
step 7. x = ln3/2ln2^2 divide both side by 2 and replace 4 with 2^2
step 8. x = ln3/4ln2.
Answer:
Step-by-step explanation:
½(x-2) = 8 + 5x
Multiply both sides by 2
2⋅½(x-2) = 2(8 + 5x)
1(x-2) = 2(8 + 5x)
Apply the distributive rule
x - 2 = 16 + 10x
Subtract x from both sides
-2 = 16 + 9x
Subtract 16 from both sides
-18 = 9x
Divide both sides by the coefficient of x
-18 ÷ 9 = 9x ÷ 9
-2 = x
Answer:
54
Step-by-step explanation:
Use PEMDAS
1. 6 x 6 + 12 + 3 x 2 (multiply 6 and 6)
2. 36 + 12 + 3 x 2 (multiply 3 and 2)
3. 36 + 12 + 6 (combine like terms, so add them)
4. 54 (final answer)
<span> -7 -7
------------------- = ---------------------
x^2 -2x -15 (x - 5)(x + 3)
x </span>≠ 5 and x ≠ -3
answer
<span>-3 and 5</span>
Answer:
the time is 6:15
Step-by-step explanation:
the reason it is 6:15 is because there is a clock on a phone where it says it's 6:15
