16xy, 24x^2y^2 are two expressions with gcf of 8xy.
A) x^2 + y^2 = 80
B) x * y = 12
What is x^2 -y^2?
B) x * y = 12
So y = 12 / x
A) x^2 + (12/x)^2 = 80
x^2 + (12/x)^2 = 80
x^2 + (144/x^2) = 80
Multiplying each side by x^2
x^4 + 144 = 80x^2
x^4 -80x^2 + 144 = 0
X = 1.355 (found by trial and error)

Answer:
128
Step-by-step explanation:
they are parralel
Well you use PEMDAS (1. Parentheses 2. Exponents 3. Multiplication and Division in order from left to right 4. Addition and Subtraction in order from left to right) to solve. you have no parentheses or exponents so you do multiplication and division first 14*14 = 196, and 196/14 is 14. Then you do addition and subtraction. 14 + 14 = 28. 28 - 14 = 14.
