Question

Find the value of K when K = 5n^2 + w. when n = 4 and w = -6.

Answer 1

• Value of k is 74

Explanation:

Here we have been provided with the values of n and w that is 4 and -6 respectively.

Equation that we have,

• k = 5n² + w

Substituting the values of n and w in the equation,

`\implies \: \sf{k \: = \: 5(4) {}^(2) \: + \: ( - 6)}`

`\implies \: \sf{k \: = \: 5(4 * 4) \: + \: ( - 6)}`

`\implies \: \sf{k \: = \: 5 \: (16) \: + \: ( - 6)}`

Multiplying 16 by 5,

`\implies \: \sf{k \: = \: 5 \: * 16 \: + \: ( - 6)}`

`\implies \: \sf{k \: = \: 80 \: + \: ( - 6)}`

`\implies \: \sf{k \: = \: 80 \: - \:6)}`

Subtracting 6 from 80,

`\implies \: \red{\bf{k \: = \: 74}}`

Therefore, value of k is 74..!!

Answer 2

`\bold{K = 5n {}^(2) + w}`

Given ,

value of n = 4

value of w = - 6

Then ,

`\bold{K = 5(4) {}^(2) + ( - 6)} \\\bold{ K = 5(16) - 6} \\\bold{ K = 80 - 6} \\ \fbox\pink{K = 74}`
