Answer:

12a^3 +2a^2 +23a+18

Step-by-step explanation:

(3a+2)(4a^2-2a+9)

we multiply 3a+2 inside the parenthesis to find the product

first multiply 3a inside second parenthesis

12a^3 - 6a^2 +27a

now multiply +2 inside second parenthesis

8a^2 - 4a + 18

Now we combine it

12a^3 - 6a^2 +27a+8a^2-4a+18

combine like terms

12a^3 +2a^2 +23a+18

How do I do this? It is a regular hexagon with a height of 30. We have to find the perimeter of it.
Sliva [168]

Answer:

The radius of a hexagon is called the apothem, which in this case is 15.

We need to know the side length which is found by the equation:

side length = apothem * 2 * (tan (180 / #sides))

side length = apothem * 2 * (tan (180 / 6))

side length = 15 * 2 * (tan (30 degrees))

side length = 30 * .57735

side length = 17.3205

We need the perimeter of the hexagon which equals the side length times six.

perimeter = 6 * 17.3205 = 103.923

51 is 17% of what number
Mrac [35]
We let x be the variable that when 17% is multiply by x it will equal 51.

Convert 17% decimal. To do this, move the % sign two places to the left and make it into a decimal point.

17% = 0.17

Now make our equation 0.17 * x = 51

Divide both sides by 0.17.

x = 300
