That equation will be
.. f(x, y) = f(3, -2)
.. 2x^2y +7x +20 = 2*3^2*(-2) +7*3 +20
2x^2*y +7x +20 = 5
Answer:
27.5
Step-by-step explanation:
The formulas jus the top line + the bottom line divided by two then multiplied by the height (dotted line)
You would simply multiply the numerators(top number). Then the denominators(bottom numbers). then simplify. <span />

Answer: No
Step-by-step explanation: If you simplify the first expression, you get 6n + 9, and if you simplify the second expression, you get 6n + 27. So they are NOT equivalent.
