X = 47 + 9y
xy = 1860
y(47 + 9y) = 1860
47y + 9y² = 1860
9y² + 47y - 1860 = 0
> using a quadratic equation solver on a calculator but you can also use the quadratic equation = [-b+/- √(b²-4ac)]/(2a)
> only integer solution is x = 12
12y = 1860
y = 155
integers are 12 and 155
No, the three given side lengths could not make a triangle.
8.4 cm is greater than 4.1 cm and 1.3 cm combined, so no matter what angle is between the two shorter sides, it is impossible to fit the 8.4 cm side.

Answer:
3x = 6
Step-by-step explanation:
Combine:
6x + 5y =16
- (6x + 2y=10)
--------------------
3y = 6, so that y = 2 (We weren't actually asked to find the solution.)
