M is directly proportional to r2.when r=2,m=14.Work out the value of r when m =224
balandron [24]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ M = k x r^2

Substitute in the values:

14 = k x 2^2

Divide both sides by 2^2 to find k:

k = 3.5

Substitute the new values in:

224 = 3.5 x r^2

Divide both sides by 3.5 to find r^2

r^2 = 64

Square root it:

r = 8

sukhopar [10]

Answer:

2n^3-3n^2-7n+3

Step-by-step explanation:

(n^2 -3n +1)(2n + 3) =\\n^2(2n) - (3n)(2n) + (1)2n + (n^2)(3) + (-3n)(3) + (1)(3)=\\2n^3 - 6n^2 + 2n + 3n^2 -9n + 3 =\\

Collecting like terms and simplifying yields

2n^3-3n^2-7n+3
