Answer:

D.Negative 12 squared +11st minus 2t squared

Step-by-step explanation:

We are given that

(-3s+2t)(4s-t)

We have to find the value of product.

(-3x+2t)(4s-t)

Multiply each term of first bracket with second bracket

-3s(4s-t)+2t(4s-t)

Now, after multiplying we get

-12s^2+3st+8st-2t^2

Combine like terms then, we get

-12s^2+11st-2t^2

Hence,the product

(-3x+2t)(4s-t)=-12s^2+11st-2t^2

Option D is true.

Billy likes to go cycling.
Agata [3.3K]

Answer:

560 metres

Step-by-step explanation:

80 cm in metres is 0.8 metres.

After 1 revolution any point on the wheel will be back to the original position before moving. 0.8 times 2, which gives us 1.6 metres. In 1 revolution the bike travels 1.6 metres.

Now 1.6 metres times 350 gives us 560.

So the answer is 560 metres.
