Question

4х -12а) при х =7 б) при х=-5​

Answer 1

а) значение выражения = 16

б) значение выражения = -32

Answer 2

To evaluate the expression 4x - 12a at different values of x, we substitute the given values of x into the expression. Let's calculate it for the given values of x:

a) When x = 7: 4x - 12a = 4 * 7 - 12a = 28 - 12a

b) When x = -5: 4x - 12a = 4 * (-5) - 12a = -20 - 12a

So, the expressions evaluated at the given values of x are:

a) 28 - 12a b) -20 - 12a
