It's linear and equation of the function is :
f ( x ) = 2x - 1
3 times 7= 21 times three =63
U . v = |u| . |v| cos 60 = 10 * 8 * 0.5 = 40 This is called the scalar (or dot) product.
Answer:
1 box has 12 chocolates
thus 20 boxes have ( 20 * 12) = 240 chocolates
1 carton has 240 chocolates (20box)
10 cartons have 240 * 10 = 2400 chocolates
