Question

Evaluate the expression below
a - cd for a = -2, c = 5, d = -3|

Answer 1

-2-(5•-3)= -2-(-15)
= -2+15
=13

Answer 2

To evaluate the expression a - cd for a = -2, c = 5, and d = -3, substitute the given values into the expression and perform the necessary operations. The value of the expression is 13.

Step-by-step explanation:

To evaluate the expression a - cd for a = -2, c = 5, and d = -3, we substitute the given values into the expression and perform the necessary operations. The expression becomes:



-2 - (5)(-3)



Now, we simplify:



-2 - (-15)



Since subtracting a negative number is the same as adding a positive number, we simplify further:



-2 + 15



Finally, we add the numbers:



13



So, the value of the expression is 13.
