If you use the first answer, the equation becomes 2x + 2y = 16.  You could subtract this from equation Q to eliminate x.

The second answer makes equation P -2x - 2y = -16.  You could add this to equation Q to eliminate x.  You can use both of these methods to eliminate the x term, but if you can only choose one, you should choose the second option.

Answer is <span>−2(x + y = 8)
cause

</span><span>−2(x + y = 8) (multiply -2 to 1st equation)
-2x - 2y = - 16
</span><span> 2x + 5y = 24
</span>--------------------add
 0 + 3y = 8 (eliminate x to solve for y)

What is the approximate area of the circle shown below?
Pani-rosa [81]

Answer:

A = 616 cm^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

A = pi (14)^2

A = pi (196)

Using 3.14 as an approximation for pi

A = 3.14 *196

A =615.44

The nearest approximation is

A = 616 cm^2
