Answer 1

Step-by-step explanation:

Given :-

Baichung’s father is 26 years younger than Baichung’s grandfather and 29 years older than Baichung. The sum of the ages of all the three is 135 years.

To Find :-

Age of each

Solution :-

Let the age of Baichung be B

Age of father = B + 26

Age of grandfather = B + 26 + 29

Age of grandfather = B + 55

Now

(B) + (B + 26) + (B + 55) = 135

3B + 81 = 135

3B = 135 - 81

3B = 54

B = 54/3

B = 18

Now

Age of Baichung = 18 years

Age of his father = 18 + 26 = 44 years

Age of grandfather = 18 + 55 = 73 years

Answer 2

Answer:

Multiply the number and variable together to get 2x. Then divide each part of the expression by 2x. The expression with the GCF factored out is 2x (x^2 + 9x + 5). Note that you must put the factored expression in parentheses and write the GCF next to it.
