Kayaks rent for $35 per day. which expression can you use to find the cost in dollars of renting 3 kayaks for a day?

$105

Step-by-step explanation:

assuming that it costs $35 dollars for renting 1 kayak per day:

3 * 35 = k   3 is for the # of kayaks and 35 is the cost

105 = k    multiply 35 w/ 3 to get the answer

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
