x^2 + 6xy + 8y2
4x^2 + 3xy + 2y^2 - 5x^2 + 2xy + 6y^2
= 4x^2 + 3xy + 2y^2 + -5x^2 + 3xy + 6y^2
Combine like terms:
= 4x^2 + 3xy + 2y^2 + -5x^2 + 3xy + 6y^2
= (4x^2 + -5x^2) + (3xy + 3xy) + (2y^2 + 6y^2)
= -x^2 + 6xy + 8y^2
Answer:
In linear expresiion 3 is the coefficient
X will be the variable and -15 will be the constant term.
Answer:
C 18
Step-by-step explanation:
1080/60 = 18
Answer:
median=mode
Step-by-step explanation:
The ratio of the sides are the same. So 6/24=x/56. This leads to x being 14.
