Question

1. Write an Expression with a Value of 12. it should contain four numbers and two different operations.

2. Place Parentheses,if needed, to make each statement true.

1. 7 + 3 x 2 + 4= 25

2. 8 (a Two Above the 8) Divided by 4 x 8 = 2

3. 16 + 8 - 5 x 2 = 14

Answer 1

1) 2*2+4+4=12
2) 1. 7 + (3 x 2) +25
2. 2/8 divided by (4x8) =2
3. 16+8 -(5x2)=14


hope this help...

Answer 2

1)
`2*2+4+4=12`

2 )Below statements are true

1. 7 + 3 ×(2 + 4)= 25

2.
`(8^2)/(4*8)=2`

3. 16 + 8-(5×2)= 14

Explanation:

1) To write an expression with a value =12 it should contain four numbers and two different operations.

`2*2+4+4=12`

2) Place Parentheses,if needed, to make each statement true.

1. 7 + 3×2 + 4= 25

In this statement one parentheses is missing i.e. bracket

New statement → 7 + 3 ×(2 + 4)= 25

7 + 3 ×2 +3× 4= 25

7 + 6 + 12= 25

25=25 now, the statement is true.

2. 8 (a Two Above the 8) Divided by 4 x 8 = 2

This statement (a Two Above the 8) means
`8^2`

so,
`(8^2)/(4*8)=2`

`(64)/(4*8)=2`

`2=2`

The statement is true.

3. 16 + 8 - 5×2 = 14

The statement is true when we solve by BODMAS

i.e. 16 + 8-(5×2)= 14

16 + 8-10= 14

24-8=14

14=14 statement is true
