Question

17. Subtract (1.5x – 2.5y) from the product of (2x - 3.5y) and (x + 4y - 1.5).​

Answer 1

Answer:2x^2 - 14y^2 + 4.5xy - 4.5x + 7.75y

Step-by-step explanation:

(2x - 3.5y)(x+4y-1.5)

2x^2 - 3.5xy + 8xy - 14y^2 -3x + 5.25y

2x^2 - 14y^2 + 4.5xy - 3x + 5.25y

now, (2x^2 - 14y^2 +4.5y -3x + 5.25y) - (1.5x - 2.5 y)

2x^2 - 14y^2 + 4.5xy - 3x + 5.25y - 1.5x + 2.5 y

2x^2 - 14y^2 + 4.5xy - 4.5x + 7.75y

Answer 2

2x^2+4.5xy-4.5x-14y^2+7.75y
