Evaluate the expression if b = 2 and c = -1. 2bc
i think u would do -1.2 x 2 x -1.2 which im pretty sure would be 2.88
n+5=10 this number is not equivelent!
N+5=10 well first we have to figure out what the n stands for
To evaluate the expression 2bc when b = 2 and c = -1, you will substitute the given values into the expression and perform the necessary calculations.
Step 1: Replace b with the value 2 and c with the value -1 in the expression 2bc.
2bc = 2(2)(-1)
Step 2: Perform the calculations inside the parentheses.
2(2)(-1) = (4) (-1)
Step 3: Multiply the numbers outside the parentheses.
(4) (-1) = -4
So, when b = 2 and c = -1, the expression 2bc is equal to -4.
