PLEASE GIVE THE CORRECT ANSWER. WILL MARK YOU AS BRAINLIST​

Answer 1

1. let no be x

3x - 13

2. length = kunit

breadth = n unit

area of rectangle = 2 ( k + n )

3. let present temp = x ° c

x -20° c

4. let no be x

9+ 2x

5. smallest 2 digit no = 99

99 - 6q

6. let no be x

1 - ⅓ x

7. let total no be x

-3x + 15 = x .
