Question

How do I solve these Algebraic Expressions?

Answer 1

1. 5

2. 6

3. 12

4. 2

Explanation:

You need to plug in the values of the variables into the expression.

1. xy - 5 when x = 5 and y = 2

(5)(2) - 5

5 × 2 - 5

10 - 5

5

2. r + s² when r = 5 and s = 1

(5) + (1)²

5 + 1

6

3.
`(c^2)/(d)` when c = 6 and d = 3

`(6^2)/(3)`

`(36)/(3)`

12

4. m - 3n when m = 8 and n = 2

(8) - 3(2)

8 - 6

2
