-x + y = 4
2x+3y= 2
-2x + 2y = 8
2x + 3y = 2
5y = 10
y= 2
-x + 2 = 4
-x = 2
x = -2
The answer is 12.56 because when you divide 43.96 by 3 1/2 that is what you get.
Answer:
k² - 18k + 81
Step-by-step explanation:
Using the given model then
(k - 9)² with a = k and b = 9
= k² - 2(k)(9) + 9²
= k² - 18k + 81
It is incorrect because those dividers prevent it from being a negative. Therefore it is wrong.
