& The product of 2 and a number is at most -6.

Explanation:

x = the unknown number

2x = the product of 2 and the unknown number

We're told that 2x is at most -6, which means since the highest 2x can go is -6. Think of this as the ceiling value.

Divide both sides by 2 to solve for x.

The division by 2 operation undoes the multiplication of 2 on x.

To graph this on a number line, plot a filled in circle at -3. Then shade to the left to indicate the set of all numbers that are -3 or smaller.

answer: the answer to your question is parallel

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
