Question

Daca x = 12 × 6 - 68 , valoarea produsului p = ( 24 - x ) × (16+x) × ( x +2) va fi : ...

Answer 1

x=12x6-68=72-68=4
p=(24-x)x(16+x)x(x+2)=(24-4)x(16+4)x(4+2)=20x20x6=400x6=2400

Answer 2

$x=12 \cdot 6-68 \\ x=72-68 \\ x=4 \\ p=(24-x) \cdot (16+x) \cdot (x+2) \\ p=(24-4) \cdot (16+4) \cdot (4+2) \\ p=20 \cdot 20 \cdot 6 \\ p=400 \cdot 6 \\ p=2400$
