Answer:

C. -20

Step by step explanation:

It appears you want the value of the expression -5² +8|-1| +(-3).

Order of operations

The order of operations tells us that the first step is to evaluate expressions in parentheses. Here, the absolute value symbols effectively serve as parentheses, so we start there.

|-1| signifies the absolute value of -1, its magnitude, or positive value. That simplifies to 1. So, your expression is ...

-5² +8·1 -3

The next step is to evaluate the term with an exponent: -5² = -(5·5) = -25.

= -25 +8·1 -3

Now, we perform the multiplication:

= -25 +8 -3

And finally, the addition/subtraction

= -17 -3

= -20

Additional comment

The expression you show in the problem statement looks like the first term is negative fifty-two. That is very different from negative five squared. An exponent is indicated using a caret (^), as -5^2, or using a superscript font, as -5². Please be careful to use appropriate math symbols where exponents are involved.
