Question

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

Answer 1

Answer:

22

Step-by-step explanation:

(3x5)+(5x3)

[(2x3)-(3x5)+(15)] + [(2x5)-(3x3)+(15)]

(6-15+15) + (10-9+15)

6+16

22

Answer 2

Answer:

22

Step-by-step explanation:

$a_1 = 3,\\b_1 = 5,\\a_2 = 5,\\b_2 = 3$

now,

$a_1*b_1+a_2*b_2$

$2a_1-3b_1+a_1b_1+2a_2-3b_2+a_2b_2$

putting the values,

$6-15+15+10-9+15$

after evaluating,

answer = 22
