please help me solve this anyone! plz don’t guess just for points this was due a few weeks ago and i have to have good grade

Step-by-step explanation:

Substitute -3 for X in the expression then solve.

-23

Step-by-step explanation:

They give us the variable's value, which is . All we have to do from here is plug it into the expression that they gave us!

So, let's do exactly that! The expression that they gave us is , and we know the value of x because they gave it to us!

Let's plug it in.:

Let's follow P.E.M.D.A.S. and our order of operations to determine what to do first. Since we have multiplication going on within parenthesis, let's do that first.

because a negative number times a positive number equates to a negative number. Now, we have the following expression:

Let's subtract this now! Remember, subtracting a number from another number is basically adding the opposite of the second number; essentially, you're following keep, change, flip. You keep the first number without doing anything to it, you change the sign of the operation, and you flip the sign of the 2nd number. Let's revise this problem now with these rules.: , now we have something that we can work with! Since both numbers are negative and are being added, we keep the sign, and just add their absolute value, leaving us with the expression being -23.

the answer is a
