Answer:
Where is the equation?
Step-by-step explanation:
(-3,7)(9,5)
midpoint formula : (x1 + x2)/2 , (y1 + y1)/2
(-3 + 9)/2 , (7 + 5)/2 = (6/2, 12/2) = (3,6) <==
The answer is 110 because if you multiply 8•16=128 and 18 cars are used, you subtract 128-18 which is 110.
If you added more context then I would probably answer your question
Answer:
6
Step-by-step explanation:
We want to expand this; (x + y)⁴
This can be written as;
(x + y)² × (x + y)²
This gives;
(x² + 2xy + y²) × (x² + 2xy + y²)
This gives;
x²(x² + 2xy + y²) + 2xy(x² + 2xy + y²) + y²(x² + 2xy + y²) = x⁴ + 2x³y + x²y² + 2x³y + 4x²y² + 2xy³ + x²y² + 2xy³ + y⁴
Simplifying gives;
x⁴ + 4x³y + 4xy³ + 6x²y² + y⁴
Thus, the coefficient of x²y² is 6
