What is the product?
makkiz [27]

Step-by-step explanation:

(4s + 2) × (5s² + 10s +3)

we know immediately the first and the last term of the result, because there is only one operation to build them :

20s³ and 6.

so, the first answer option is already eliminated.

let's multiply

4s×5s² + 4s×10s + 4×3s + 10s² + 20s + 6

20s³ + 40s² + 12s + 10s² + 20s + 6

20s³ + 50s² + 32s + 6

so, the last answer option is correct.

Neporo4naja [7]

Answer:

Fraction=1/5=0.2

Step-by-step explanation:

If the student is 4m away from the school bell and moves 20m away, it means that he is 5 times more distant from the school bell and therefore should listen 5 times less, that is, 1/5 of the original sound.
