I believe it is 5, the picture is kind of blurry but if 5 is a answer choice it is most likely 5
5x - 14y = 22 ⇒ 5x - 14y = 22
-6x + 7y = 3 ⇒ <u>12x - 14y = -6</u>
<u>-7x</u> = <u>28</u>
-7 -7
x = -4
5x - 14y = 22
5(-4) - 14y = 22
-20 - 14y = 22
<u>+ 20 + 20</u>
<u>-14y</u> = <u>42</u>
-14 -14
y = -3
(x, y) = (-4, -3)
3451 now I’m just putting 20 characters to answer lol
The pattern that ends in 5 or 0 is the 5's .<span />
A= 3.14* 12^2
= 3.14* 144
= 452.16cm^2
