To solve this problem you must apply the proccedure shown below:
If [tex](a)(b)=2a+b[/tex], you have that:
[tex](2)(5)=(2)(2)+5=9[/tex]
Because [tex]a=2[/tex] and [tex]b=5[/tex]
Therefore, as you can see, the answer is: [tex]9[/tex]
Answer
9
Explanation
a*b ⇒ 2a + b
2*5 ⇒ ?
Comparing a*b and 2*5, we can say that;
a = 2 and
b = 5
So, substituting a with 2 and b with 5 in the equation 2a + b we have,
2*5 ⇒ 2(2) + 5
⇒ (2×2) + 5
⇒ 4 + 5
⇒ 9
