Area of composite shapes!!

Either 24 cm^2 or 28 cm^2

Step-by-step explanation:

I can't remember if the calculated area of the part of the shape which is removed is halved or not, if it's cut in half then the answer is 28 otherwise it's 24.

It's either

32 - 8 = 24

32 - 4 = 28

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (7, 450) and (x₂, y₂ ) = (14, 401)

m = = = - 7, thus

y = - 7x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (7, 450), then

450 = - 49 + c ⇒ c = 450 + 49 = 499

y = - 7x + 499 → A
