Answer:

w=5

Step-by-step explanation:

First you have to write out the equation. Then you distribute negative 4 to 3w then you distribute -4 to -1 you get 4. Then you need to combine like terms and you get 3W. then you need to subtract four from each side you get 15 equals 3W then divide aside by three and you get W equals five

12. Factor completely: 64x^3 + 729
Dafna1 [17]

Answer:

(4 x + 9) (16 x^2 - 36 x + 81)

Step-by-step explanation:

Factor the following:

64 x^3 + 729

64 x^3 + 729 = (4 x)^3 + 9^3:

(4 x)^3 + 9^3

Factor the sum of two cubes. (4 x)^3 + 9^3 = (4 x + 9) ((4 x)^2 - (4 x) 9 + 9^2):

(4 x + 9) ((4 x)^2 - 4 9 x + 9^2)

4×9 = 36:

(4 x + 9) ((4 x)^2 - 36 x + 9^2)

Multiply each exponent in 4 x by 2:

(4 x + 9) (4^2 x^2 - 36 x + 9^2)

4^2 = 16:

(4 x + 9) (16 x^2 - 36 x + 9^2)

9^2 = 81:

Answer: (4 x + 9) (16 x^2 - 36 x + 81)

Identify the pattern for the following sequence. Find the next three terms in the sequence.
Zina [86]
The answer is B.

-9/3= -3, which means that each number is getting multiples by -3. Therefore, we can eliminate A and D. 27•-3=-81, so we can eliminate C. We are left with B, and we can check this by making sure that each number is correctly multiplied by -3.

The time t required to travel a fixed distance varies inversely as the speed r. it takes 5h to drive the fixed distance at a spe
Pavel [41]
Let t be time and r be rate, then if time varies inversely with the rate, the equation is t= \frac{k}{r}.  If it takes 5 hours to drive a fixed distance at a rate of 80, we can sub those values in to solve for the constant of variation, k.5= \frac{k}{80}.  Solve for k by multiplying 5 and 80 to get that k = 400.  Now let's find a new time t when r is a rate of 70.  We will use that k value to do this: t= \frac{400}{70} and find that it will take 20 hours to drive the distance at 70 mph when it takes 5 hours to drive the distance at 80 mph.  Makes sense that it takes longer to drive a fixed distance when you are going slower.
