Kia rides her bicycle at 20 miles per hour. Which equation represents the situation?
Let h represent the hours traveled.
Let d represent the distance traveled.
O d = 20h
0 h = 200
O d = 20 + 1
O h = 20 -
Please help me

(A)d=20h

Step-by-step explanation:

If Kia rides her bike at 20 miles per hour.

20 miles per hour is referred to as the Kia's Speed.

Now we know that:

Given:

Substituting these three into the formula above, we have:

Cross multiply

d=20h

The correct option is A.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
