Prove that 3a + 3b is equivalent to 3(a + b) when a = 4 and b = 3.

Step-by-step explanation:

= 3a+3b

or, 3×4+3×3

or, 12+9

or, 21

again,

= 3(a+b)

or, 3×(4+3)

or, 3×7

or, 21

hence 3a+3b is equivalent to 3(a+b) is proven

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

multiple all that
