Question

2 + 3а при а = 4, -5=

Answer 1

при а=4

2+3*4=14

при а=-5

2+3*(-5)=-13

Answer 2

To evaluate the expression 2 + 3a when a = 4, we substitute the value of a into the expression:

2 + 3a = 2 + 3(4)

Now we simplify the expression:

2 + 3(4) = 2 + 12 = 14

So, when a = 4, 2 + 3a equals 14.

Regarding the equation -5 = ?, it seems incomplete or missing an expression or variable on the right side. Could you please provide more information or clarify the equation?
