Hello!

To find the area of a hexagon you do 3\frac{3 \sqrt{3} }{2} } a^{2} where a is one of the sides

Since the perimeter is 60 we can do 60/ the sides of the shape

60/6 = 10

So one side is equal to 10

you put that into the formula to get the area of a hexagon and you get 259.81

Hope this helps!

If 2n + 3(2- 2n) = 14 what is the value of n? (Please give the correct answer, I will give brainliest)
allochka39001 [22]

Answer:

  n = -2

Step-by-step explanation:

Eliminating parentheses, you have ...

  2n +6 -6n = 14

Combining terms and subtracting 6, you get ...

  -4n = 8

Dividing by the coefficient of n gives ...

  n = -2

_____

<em><u>Check</u></em>

  2(-2) +3(2 -2(-2)) = 14

  -4 +3(2+4) = 14

  -4 +3(6) = 14

  -4 +18 = 14 . . . . answer checks OK

At age 40 you deposit $150 at the end of each month into an IRA that pays 4% interest compounded monthly. At age 65, what will t
Svetlanka [38]

Answer:

Annuity= 242.4

Step-by-step explanation:

This is a compound interest problem.

The total amount at the end of 25 years will be

A = p(1+r/n)^(nt)

A = 150(1+(0.04/(25*12)))^ ((25*12)(25))

A= 150(1 + 0.04/300)^ (300*12)

A = 150(1+ 0.0001333)^ 3600

A = 150(1.0001333)^ 3600

A = 1500(1.615828808)

A= 242.374

A= 242.4 to the nearest cent
