Question

[6] Evaluate 3K2 - 6K for K = 5
(A) 45 (B) 195 (C) 0 (D) 75​

Answer 1

A

Explanation:

To evaluate 3K^2 - 6K for K = 5, we substitute K = 5 into the expression:

3K^2 - 6K = 3(5)^2 - 6(5)

Simplifying, we get:

3(25) - 30 = 75 - 30 = 45

Therefore, 3K^2 - 6K, with K = 5, is equal to 45.

Answer 2

option:-

• 
  `\large\tt \blue{a)45}`

`\:`

Given:-

• k = 5
• 3k²-6k

Now , Put the given value of k in eqⁿ

• 
  `\large \tt{3 {k}^(2) -6 k}`

`\:`

• 
  `\large \tt{3 ({5})^(2) -6 (5)}`

`\:`

• 
  `\large \tt{3 (25) -6 (5)}`

`\:`

• 
  `\large \tt{75 - 30}`

`\:`

• 
  `\underline{ \boxed{\large \tt{\red{ \: 45 \: }}}}\green✓`

`\:`

hope it helps!:)
