Question

-2(4n+1)+3(2n-1) якщо n=2

Answer 1

Якщо n=2 то -2(4n+1)+3(2n-1) буде -2(4*2+1)+3(2*2-1)

Тож -2(4*2+1)+3(2*2-1)=

-2(8+1)+3(4-1)=

-16+(-2)+12-3=

-18+9=-9

Answer 2

To evaluate the expression -2(4n+1) + 3(2n-1) when n=2, we substitute the value of n into the expression and simplify:

-2(4n+1) + 3(2n-1)

Replacing n with 2:

-2(4(2)+1) + 3(2(2)-1)

Simplifying within the parentheses:

-2(8+1) + 3(4-1)

-2(9) + 3(3)

Performing the multiplications:

-18 + 9

Finally, adding the terms together:

-18 + 9 = -9

Therefore, when n=2, the expression -2(4n+1) + 3(2n-1) evaluates to -9.
