Answer:
Missing number is 5.
Step-by-step explanation:
The distributive property of multiplication over addition/subtraction states that
(a×b)+(a×c) = a(b+c)
(4×1)+(4×5)=4×(1+c)
comparing property to given question
a =4 , b= 1 and c=5
so we can say missing number 5 beacuse of where L.H.S. , 5 is placed to C that's means In R.H.S. also 5 in placed to C.
