Answer 1

А=4
2+3*4= 14
2+3*(-5)= -13

Answer 2

1)2+3а, при а=4
2+3×4=2+12=14
Ответ: 14
2)2+3а, при а=-5
2+3×(-5)=2+(-15)=-13
Ответ: -13

Answer 3

To find the value of the algebraic expression 2 + 3a, where a takes the values a = 4 and a = -5, we can substitute the values of a into the expression and compute the result.

1. For a = 4: 2 + 3(4) = 2 + 12 = 14

2. For a = -5: 2 + 3(-5) = 2 - 15 = -13

So, the values of the expression for the given values of a are:

When a = 4, the value is 14. When a = -5, the value is -13.
