+ 9n) + 3(4n- 7n)

Answers

Answer:

n = 0 or n = -9/16

Step-by-step explanation:

Solve for n:

2 (8 n^2 + 9 n) - 9 n = 0

Hint: | Write the quadratic polynomial on the left hand side in standard form.

Expand out terms of the left hand side:

16 n^2 + 9 n = 0

Hint: | Factor the left hand side.

Factor n from the left hand side:

n (16 n + 9) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

n = 0 or 16 n + 9 = 0

Hint: | Look at the second equation: Isolate terms with n to the left hand side.

Subtract 9 from both sides:

n = 0 or 16 n = -9

Hint: | Solve for n.

Divide both sides by 16:

Answer: n = 0 or n = -9/16

Find the area of the following circle r=9 yd

Answers

The area of the circle is given by the formula A=pi*r^2 if the radius is 9yd you can simply sub it into the formula. A=pi*9^2 which then becomes A=pi*81 you can then put this into your calculator and you get approximately A=254.469 yds if you are not allowed a calculator use pi as 3.14 A=3.14*81 which gives you 254.34yds (close enough). Hope this helps
