Question

2a-2b при a=-2 при b=8

Answer 1

(2*-2)-(2*8)=-4-16=-20

Answer 2

2a-2b при а =-2 ;b= 8: 2×-2-2 ×8 = -16

Answer 3

To evaluate the expression 2a - 2b when a = -2 and b = 8, simply substitute the values of a and b into the expression and perform the calculations:

2a - 2b = 2(-2) - 2(8)

Now, perform the operations:

2a - 2b = -4 - 16

Finally, compute the result:

2a - 2b = -20

So, when a = -2 and b = 8, the value of 2a - 2b is -20.
