Area of rectangle is the multiplication between the sides.


The first rectangle:


A = (2x + 5) . (3x - 2)

A = 2x . 3x - 2 . 2x + 5 . 3x - 2 . 5

A = 6x² - 4x + 15x - 10

A = 6x² + 11x - 10


The second rectangle:


A = (5y + 5) . (2y - 3)

A = 5y . 2y - 3 . 5y + 5 . 2y - 3 . 5

A = 10y² - 15y + 10y - 15

A = 10y² - 5y - 15

Answer:

  The value of f(1) is larger than the value of f(3)

Step-by-step explanation:

Put the numbers in the equation and do the arithmetic.

  f(1) = -2(1²) +3(1) +10 = 11

  f(3) = -2(3²) +3(3) +10 = 1

11 is larger than 1, so f(1) is larger than f(3).
