very eazy question guyssssss

Answer 1

Answer :-

Given value of y = -5

equation

= $\frac{4}{5} y^3 + \frac{1}{5} y^2 - 6y - 65$

by putting value of y

= $\frac{4}{5} ({-5}^{3}) + \frac{1}{5} ({-5}^{2}) - 6(-5) - 65$

= $\frac{4}{5} (-125) + \frac{1}{5} 25 + 30 - 65$

= 4 × (-25) + 1×5 + 30 - 65

= -100 + 5 + 30 - 65

= 35 - 165

= -130

Answer 2

4 ( -25 ) + 5 + 30 - 65

= -100 + 35 - 65

= -120
