Answer:
Let me try...
Step-by-step explanation:
let's combine like terms first to simplify the equation
we need to only combine the variables with the same variable.
3a+5a would make 8a
and 4b+10b would be 14b
but we cannot combine 8a and 14b
so the equation remains as 8a+14b
Answer:
C
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(7x - 40) is an exterior angle of the triangle, then
7x - 40 = 3x + 3x - 20
7x - 40 = 6x - 20 ( subtract 6x from both sides )
x - 40 = - 20 ( add 40 to both sides )
x = 20 → C

Answer:
125x³ − 150x²y + 60xy² − 8y³
Step-by-step explanation:
(5x − 2y)³
₃C₀ (5x)³ (-2y)⁰ + ₃C₁ (5x)² (-2y)¹ + ₃C₂ (5x)¹ (-2y)² + ₃C₃ (5x)⁰ (-2y)³
(1) (125x³) (1) + (3) (25x²) (-2y) + (3) (5x) (4y²) + (1) (1) (-8y³)
125x³ − 150x²y + 60xy² − 8y³
