Let \( n = 2.5 \).

What is the value of \( 2n(6n - 3) + 4n \)?

n = 2.5 , 2 n ( 6 n − 3 ) + 4 n = 12 n 2 − 6 n + 4 n = 12 n 2 − 2 n 12 n 2 − 2 n = 12 ∗ ( 2.5 ) 2 − 2 ∗ 2.5 = 12 ∗ 6.25 − 5 = 75 − 5 = 70

2 n ( 6 n − 3 ) + 4 n substitute n = 2.5
2 ∗ 2.5 ( 6 ∗ 2.5 − 3 ) + 4 ∗ 2.5 = 5 ( 15 − 3 ) + 10 = 60 + 10 = 70

The value of the expression 2 n ( 6 n − 3 ) + 4 n when n = 2.5 is 70 . This is found by substituting n into the expression and simplifying step by step. After evaluating the components, the final result is 70 .
