If a x b = 2a - 3b + ab, then 3 x 5 + 5 x 3 is equal to?

0

Step-by-step explanation:

We know that,

a x b = 2a - 3b + a

We apply this to our problem to identify a and b,

(3 x 5) + (5 x 3)

Part 1: (3 x 5)

a = 3 , b= 5

Apply,

2a - 3b + a

(2 x 3 - (3 x 5) + 3 ) =

(6 - 15 + 3) = -6

Part 2: (5 x 3)

a = 5 , b = 3

Apply,

2a - 3b + a

(2 x 5 - (3 x 3) + 5) =

(10 - 9 + 5) = 6

Putting all together,

(3 x 5) + (5 x 3) =

-6 + 6 = 0
