We can only combine 5x²y and x²y because they have the same variables. combining like terms,

sum = 5x²y + (2xy² + x²y)
sum = (5x²y + x²y) + 2xy²
siimplifying,
sum = 6x²y + 2xy²

thus, the sum of the expressions given above is 6x²y + 2xy².
is it a bonomial or monomial .\?

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6
