To solve this problem you must apply the proccedure shown below:

If
(a)(b)=2a+b, you have that:


(2)(5)=(2)(2)+5=9

Because
a=2 and
b=5

Therefore, as you can see, the answer is:

Answer

9


Step-by-step 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,

a*b ⇒ 2a + b

2*5 ⇒ 2(2) + 5

⇒ (2×2) + 5

⇒ 4 + 5
