Which of the following expressions are equivalent to -8 - (-1) - 5? Choose 2 answers:
--8-1-5
-8_15
-8+(-1) + (-5)
(8+1) -5
-(8-1+5)

Options B and E are correct

Step-by-step explanation:

B and E

Step-by-step explanation:

⇒ The –(–1) part of the expression is that same as + 1:

Option B: –8 + 1 – 5

⇒ This means you can eliminate option A because it’s incorrect, which means that option C is also incorrect since it’s equivalent to option A. Option D is incorrect too becasue the expression doesn’t have a negative sign next to the 8. This concludes that option E is the other correct option. We can make sure it is correct:

–(8 – 1 + 5)  ⇒  the negative on the outside of the parentheses basically has an imaginary –1. So it is now converted to –1(8 – 1 + 5)

⇒ Distribute the –1 into the parentheses to get:

–8 –(–1) – 5. Which is equvalent to the question’s expression and also equivalent to option B.

Option B and E
