11/6 = n + 7/9 what is n
LuckyWell [14K]

Answer:

n = 19/18

Step-by-step explanation:

11/6 = n + 7/9

To isolate n, we want to subtract 7/9 from both sides.

11/6 - 7/9 = n

To subtract these fractions, they need to have the same denominator. A common multiple of 6 and 9 is 18.

11/6 ⇒ 33/18

7/9 ⇒ 14/18

33/18 - 14/18 = 19/18

n = 19/18

Hope this helps!

Find the area of a regular hexagon whose apothem is 1.7cm and a side length is 2cm
tia_tia [17]

Answer: 10.2 cm^2

Step-by-step explanation:

A regular hexagon is composed of 6 regular triangles whose area is equal to half of the product of the apothem and side.

A - triangle = (1/2)(a)(s) = (1/2)(1.7 cm)(2 cm) = 1.7 cm²

Multiplying this area by 6 to get the area of the hexagon gives us the answer which is 10.2 cm².
