Original stack :
Melon = 45
Grape fruits = 60
Mini version :
Grapefruit = 24
Using grapefruit ; we can obtain the scale factor;
60 : 24 = 2.5 : 1

Answer:
Step-by-step explanation:
Almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit. Many people use linear equations every day, even if they do the calculations in their head without drawing a line graph.
(6+3i)(6-3i) =
(6 x 6) (6 x -3i) = 36 - 18i
(3i x 6) (3i x 3i) = 18i + 9i^2
36 - 18i + 18i + 9i^2
36 + 9i^2
