Area of square = x^2
If length is multiplied by 3, then each side of square is now 3x
new Area = (3x)^2 = (3x)*(3x) = 9x^2
So the Area has increased by a factor of 9.
In general, the Area will always increase by a factor which is the square of the factor applied to the side length.
Answer:
Step-by-step explanation:
(g-f)(x) = 9x³ - 4x² + 10x - 55 - [ 4x³ +3x² - 5x + 20]
To remove the parenthesis, take - inside, multiply f(x) by -1
= 9x³ - 4x² + 10x - 55 - 4x³ - 3x² + 5x - 20
Now, bring like terms together,
= 9x³ - 4x³ - 4x² - 3x² + 10x + 5x - 55 - 20
= 5x³ - 7x² + 15x - 75
Answer:
(20-10)/(4-2)= 10/2= 5 miles/day
