Tammy completed the following steps to simplify the expression
-5x²y - 3xy² - 2(4y + 2) - 2.5x²y.

-5x²y - 3xy² - 2(4y) + 2(2) - 2.5x²y

-5x²y - 3xy² - 8y + 4 - 2.5x²y

(-5x²y - 3xy² - 2.5x²y) - 8y + 4

(-5 - 3 - 2.5)x²y - 8y + 4

-10.5x²y - 8y + 4

Explain why Tammy's solution is incorrect. Then show how to correctly simplify the expression.

the third term wasn't distributed properly the -2 has to multiply by +2 = -4

Step-by-step explanation:

-5x^2y - 3xy^2 - 2(4y+2) - 2.5x^2y

-5x^2y - 3xy^2 - 8y - 4 - 2.5x^2y

-7.5x^2y - 3xy^2 - 8y - 4

answer

false

explanation

these practices describe the manner the land use outcome is attained. land management methods implemented by corporations are a mandatory because they are a driver for better land use results economically, socially and environmentally. corporations are required to understand the connection between land use , and land management practices to support sustainable land use policies
