Answer:

[tex]-85[/tex]

Step-by-step explanation:

[tex]-x+y(x-4)x[/tex]

[tex]-\left(-5\right)+\left(-2\right)\left(\left(-5\right)-4\right)\left(-5\right)[/tex]

Follow the PEMDAS order of operations:-

Calculate within the parentheses:-

[tex]\left(-5\right)-4[/tex]

[tex]=-9[/tex]

[tex]-\left(-5\right)+\left(-2\right)\left(-9\right)\left(-5\right)[/tex]

Multiply:-

[tex]\left(-2\right)\left(-9\right)\left(-5\right)[/tex]

Rule:- [tex](-a) \times (-b)=a\times b[/tex]

[tex]2\cdot \:9=18[/tex]

[tex]=18\left(-5\right)[/tex]

[tex]18\left(-5\right)=-18\cdot \:5=-90[/tex]

[tex]=-\left(-5\right)-90[/tex]

[tex]-\left(-5\right)-90[/tex]

Rule:- [tex]-(-a)=a[/tex]

[tex]-\left(-5\right)=5[/tex]

Subtract:-

[tex]5-90[/tex]

[tex]=-85[/tex]
