Translate the sentence into an equation Five less than the product of 2 and a number is equal to 7.

2x - 5 = 7

Step-by-step explanation:

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

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
