Answer:
59
Step-by-step explanation:
3^3=27
2x27=54
27+54+5=59
We can solve this using the formula nth term = a+(n-1)d
so the 10th term will be 87
75th term will be 132
and nth will be 9n-3
Answer:
y/3
Step-by-step explanation:
According to the conditions :
y + y/3 - x = y
y + y/3 - y = x
(3y + y - 3y )/3 = x
y/3 = x
Answer:
- 4x² + 6xy - y²
Step-by-step explanation:
8x² + 3xy + 4y² - 12x² + 3xy - 5y² ← collect like terms
= (8x² - 12x² ) + (3xy + 3xy) + (4y² - 5y²)
= - 4x² + 6xy - y²
