Hello from MrBillDoesMath!
Answer:
Yes.
Discussion:
There appears to be a functional relationship based on the data gives. In particular, each value of "x" has a defined (dependent) value of "y"

Answer: D, B, C ,A
A being the greatest
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the larger number = x
Let the smaller number = y
x = 2*y + 8
x * y = 234 Put the first equation into the second.
(2y + 8)*y = 234 Remove the brackets
2y^2 + 8y = 234 Subtract 234 from both sides
2y^2 + 8y - 234 =0 Factor out 2
2(y^2 + 4y - 117) = 0 Divide by 2
y^2 + 4y - 117 = 0
(y + 13)(y - 9)
y = 9 is one answer
x * y = 234
x * 9 = 234 Divide by 9
x = 234/9
x = 26
The two numbers are 9 and 26
