Question

Find the value of K when K = 3n2 + w when n = 2 and w = - 10 .

Answer 1

Given: K = 3n² + w, where n = 2 and w = - 10.

To find: The value of K.

Solution: We provided with K = 3n² + w (an equation) and asked to find the value of K. Also provided with the value of n and w as 2 and -10 respectively.

No rocket science! Simply plugin the given value of n and w in K = 3n² + w to get the value of K.

Let's dive in!

$\rightarrow{k = 3 {n}^{2} + w} \\ \rightarrow{k = 3( {2)}^{2} + ( - 10}) \\ \rightarrow{k = 3(4) - 10} \\ \rightarrow{k = 12 - 10} \\ \rightarrow{k = 2}$

Note: K = k (dunno how to write capital one in latex.

Hence, the required value of K is 2.
