Answer:
B.4x-3y
Step-by-step explanation:
(3x-5y)+(x+2y)
Combine like terms
3x+x -5y +2y
4x -3y
Answer:
(5x + 1)x(2x^2+1)
Step-by-step explanation:
<=> cosx = +1/2 or cosx = -1/2;
cosx = +1/2 => x = +π/3 + 2kπ, where k is an integer or x = -π/3 + 2kπ, where k is an integer;
cosx = -1/2 => x = +2π/3 + 2kπ, where k is an integer or x = -2π/3 + 2kπ, where k is an integer;
Answer:
Step-by-step explanation:
Are you trying to find a variable expression? the product of 86 means multiplication so 86*n or 86n. Other than that I dont understand the question.
