Answer 1

Ответ: Якщо а=5 то а•6 + 19= 5•6+19=59

Якщо а=7 то а•6+19= 7•6+19 = 61

Answer 2

I can help you with finding the value of expressions with variables. The expression you asked is $a \cdot 6 + 19$, and you want to know its value when $a = 5$ and when $a = 7$. To find the value of an expression with a variable, you need to substitute the given value of the variable into the expression and then perform the arithmetic operations. For example, when $a = 5$, you can write:

$$ a \cdot 6 + 19 = 5 \cdot 6 + 19 = 30 + 19 = 49 $$

Similarly, when $a = 7$, you can write:

$$ a \cdot 6 + 19 = 7 \cdot 6 + 19 = 42 + 19 = 61 $$

Therefore, the value of the expression $a \cdot 6 + 19$ is $49$ when $a = 5$ and $61$ when $a = 7$.
