I need help on this please
Leya [2.2K]

The expression we have is:

2xy\cdot xy^2

And we are given some values for x and y:

\begin{gathered} x=2 \\ y=4 \end{gathered}

The first step will be to substitute the given values into the expression:

2(2)(4)\cdot(2)(4)^2

The next step is to solve 4^2 which is equal to 16:

2(2)(4)\cdot(2)(16)

And then we solve the multiplications, 2(2)(4) is equal to 16 and (2)(16) is equal to 32:

16\cdot32

Solving this final multiplication we get the result:

512

Answer: 512

zepelin [54]

Answer:x=7

y=2 5/6

Step-by-step explanation:

6(x-5)=12

6x-30=12

6x=12+30

6x=42

6x/6=42/6

x=7

6y-5=12

6y=12+5

6y=17

6y/6=17/6

y=2 5/6

Hey I need to survey 10 people who play video games so please answer or comment your answers down below :)
nikklg [1K]

Playing video games helps me if I have a rough time, I started around 2019. I play adventour type video games, not sure if raft counts, but that is a game I play too often with my friends. I think that video games probably could be played in cars as well but I dont know what else it can be or will be played on. Definitely will not be a single platform, people are too greedy everyone wants a better state then others. (not sure if that makes sense)

hope this helps :))
