You can use expanded form: 4 X 700, 4 X 50, 4 X 4, = 3016.
You can use the Distributive Property of Multiplication: (4 X 500) + (4 X 254) = 3016.
Given:
land area of Alaska: 1,700,000 square kilometers
land area of Florida: 0.10 of Alaska
To find the land area of Florida, we multiply its decimal to the land area of Alaska
1,700,000 sq. km * 0.10 = 170,000 square kilometers.
The land area of Florida is 170,000 square kilometers. It is equal to 0.10 or 10% of the land area of Alaska.<span />
This is just about substitution!! 9(5)-3(5), 3 • 5 = 15
9 • 5 = 45
so Now you have, 45 - 15 = 30
(x^2 + 3)(5x + 9)
5x^3 + 9x^2 + 15x + 27
