Question

5x(8+9)=(_+8) +(_x9) what is the missing term/s

Answer 1

Answer:

5

Step-by-step explanation:

1) as 8+9=15*5=85-------1)

2) 5+8=13 and 8*9=72

so 13+72=85--------2)

from 1 and 2 we conclude that LHS=RHS and the missing words are 5 and 8

Answer 2

The missing terms is 5 i.e 5 × (8 + 9) =  (5 × 8) +(5 × 9)

Given:

5 × (8 + 9) = (_ × 8) +(_ × 9)

To find:

What is the missing term/s

Solution:

To solve this equation, use the distributive property of multiplication

The distributive property of multiplication over addition states that

a × (b + c) = (a × b) + (a × c)

The statement given is

5 × (8 + 9) =  (_ × 8) +(_ × 9)

Compare the above formula with the statement

=> a = 5, b = 8 and c = 9

Hence, 5 × (8 + 9) =  (5 × 8) +(5 × 9)

This can be verified as follows

=> 5 × (8 + 9) = 5 × 17 = 85

=> (5 × 8) +(5 × 9) = 40 + 45 = 85

Therefore,

The missing terms is 5 i.e 5 × (8 + 9) =  (5 × 8) +(5 × 9)
