25 Points ❣️ Directions: Identify the constant/s and variable/s in each algebraic expression.

Given Constant. Variable

1. 7׳
2. 3a² + 1
3. 10 × + y
4. 25r³ + 10s²
5. 40a⁵b⁴ - 11

1. variable = x

2. constant = 1,  variable = a

3. variables = x and y

4. variables = r and s

5. constant = -11, variables = a and b

Step-by-step explanation:

1. variable = x

2. constant = 1,  variable = a

3. variables = x and y

4. variables = r and s

5. constant = -11, variables = a and b

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
