$Log(\frac{M}{N}) = 4 \implies \frac{M}{N} = 10^4\\\\Log(\frac{P}{N}) = 5 \implies \frac{P}{N} = 10^5\\\\\implies P = 10M$

Simplify this expression. 12x2(3x4 − 2x)

musickatia [10]

Answer:

$36*x^6-24*x^3$

Step-by-step explanation:

We can simplify the expressio using the product rule. The exponents will add up when multiplied with each other:

$=12*x^2*(3*x^4-2*x)$

$=12*3*x^(2+4)-12*2*x^(2+1)$

$=36*x^(6)-24*x^(3)$

The answer is B

$36*x^6-24*x^3$

Tcecarenko [31]

Answer:

3.08 miles

Step-by-step explanation:

Total distance = 10 miles
Total time = 2 hours
Distance walked = x
Speed walked = 2 mph
Distance cycled = 10 - x
Speed cycled = 15 mph

Using the given data we can have the equation below to the time:

x/2 + (10 - x)/15 = 2
30x/2 + 30(10 - x)/15 = 30(2)
15x + 20 - 2x = 60
13x = 60 - 20
13x = 40
x = 40/13
x = 3.08 miles rounded to 2 decimal places
