Statement Reason
1.
Given
2.
Subtraction property of equality
3.
Multiplication property of equality
W=2L-3
W*L=193
replace W with 2L-3: (2L-3)L=193
2L^2-3L-193=0
Cannot factor
are you sure the numbers are correct?
If it cannot be factored, use the quadratic formula to find out L, then you can find out W
use the Pythagorean theorem to find the diagonal. I don't see an easier way.
Answer:
Is non-linear
Step-by-step explanation:
It is a quadratic function
