Which values from the set {−6, −4, −2, 0, 2, 4, 6} satisfy this inequality? 3 +1/2x ≥ 4

A). –4, –2 and 0 only

B). 2, 4 and 6 only

C). 0, 2 and 4 only

D). –6, –4, –2 and 0 only

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

i belive those are the ones that are under 90 degreese.

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