Answer:

For this case we first calculate the area of the complete rectangle.

We have then:

A1 = (8.5) * (11)

A1 = 93.5

Then, we calculate the area of each circle:

A2 = pi * r ^ 2

A2 = (3.14) * (2/2) ^ 2

A2 = 3.14

The total area is given by:

A = A1 - 4 * A2

A = 93.5 - 4 * (3.14)

A = 80.94 in ^ 2

Answer:

A) 80.94

What is y={-\dfrac{1}{3}}x-9y=− 3 1 x−9y, equals, minus, start fraction, 1, divided by, 3, end fraction, x, minus, 9 written i

Kobotan [32]

Answer:

$x+3y=-27$

Step-by-step explanation:

We are given that

$y=(-\frac{1}{3})x-9$

We have to find the standard form of given equation

$y=\frac{-x-27}{3}$

$3y=-x-27$

By using multiplication property of equality

$x+3y=-27$

We know that

Standard form of equation

$ax+by=c$

Therefore, the standard form of given equation is given by

$x+3y=-27$
