Answer:
[tex]\huge\boxed{Answer\hookleftarrow}[/tex]
Given,
[tex]x = 7[/tex]
Substitute the value of 'x' in the equation 3x (x - 2).
One way :-
[tex]3x(x - 2) \\ = 3 \times 7(7 - 2) \\ = 21(5) \\ = 21 \times 5 \\ = 105[/tex]
Second way :-
[tex]3x(x - 2) \\ = 3x {}^{2} - 6x \\ = 3 \times (7) {}^{2} - 6(7) \\ = (3 \times 49) - (6 \times 7) \\ = 147 - 42 \\ = 105[/tex]
✐ The answer is 105.
