Javeria Malick · Accepted Answer

Final Answer : A, Explanation :   The given expression simplifies to -0.7x^2 - 0.4x + 1.15 by combining like terms:   x 5 − 3 5 x = − 2 5 x = − 0.4 x \frac{x}{5} - \frac{3}{5}x = -\frac{2}{5}x = -0.4x 5 x ​ − 5 3 ​ x = − 5 2 ​ x = − 0.4 x  ,   2 5 + 3 4 = 8 20 + 15 20 = 23 20 = 1.15 \frac{2}{5} + \frac{3}{4} = \frac{8}{20} + \frac{15}{20} = \frac{23}{20} = 1.15 5 2 ​ + 4 3 ​ = 20 8 ​ + 20 15 ​ = 20 23 ​ = 1.15  , and the   x 2 x^2 x 2   term remains unchanged.
