2.5 x 2x=5x
2.5 x 5=12.5
2.5 x 5x=12.5x
2.5 x 2=5

Answer:

-14.5

Step-by-step explanation:

[tex]\sf 2.5(2x - 5) - (5x + 2)[/tex]

Remove parentheses from (5x+2):-

[tex]\sf 2.5(2x-5)-5x-2[/tex]

Use the distributive property to multiply 2.5 by 2x−5.

[tex]\sf 5x-12.5-5x-2[/tex]

Combine like terms:-

[tex]\sf (5x-5x)+(-12.5-2)[/tex]

[tex]\sf (5x-5x)=\boxed{0}[/tex]

[tex]\sf -12.5-2=\boxed{-14.5}[/tex]
