Answer:

Well if x = 2 and y = 3 then that would be 28

Step-by-step explanation:

First replace the x with 2 and multiply it with 6 getting 12 and then do the same with 7y and turn the y into 3 multiply it getting 21 then you add that with the 12 we got and get 33 then subtract it by that 5 and finish with 28!

Taylor earn $5 each time she walks her neighbors dog she has already earned $25 write and solve an equation to find o....Le list
vampirchik [111]

Complete question :

Taylor earns $5 each time she walks her neighbor's dog. She has already earned $25. Write and solve an equation to find out how many more times Taylor needs to walk the dog to earn enough to buy a bike that costs $83.

Answer:

12

Step-by-step explanation:

Amount earned for walking dog = $5 per walk

Amount already earned = $25

How many more times dog needs to be walked to buy a bike which costs $83

Target amount = 83

(Target amount - already earned amount) / amount earned per Walk

(83 - 25) / 5

58 / 5

= 11.6

Hence, Taylor needs to walk her neighbor's dog 12 more times

If (x - 3) represents the side of a cube, what is the<br>polynomial that represents its volume?​
hichkok12 [17]

Answer:

x³ - 9x² + 27x - 27

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ( s is the measure of the side ) , thus

V = (x - 3)³

   = (x - 3)(x - 3)(x - 3) ← expand the second/ third factors using FOIL

   = (x - 3)(x² - 6x + 9) ← distribute

   = x³ - 6x² + 9x - 3x² + 18x - 27 ← collect like terms

   = x³ - 9x² + 27x - 27
