Question

1) Evaluate the expression for the given value of the variable.
x - 9; x = 15

2) Evaluate the given expression for x = 3 and y = 5.
3x + 2y

3) Evaluate the given expression for s = 5.
s² + 7s – 2

4) Evaluate the given expression for m = 1/3.
18m² + 3m + 7

5) Evaluate the given expression for x = 3 and y = 5.
x² + y²

6) Evaluate the given expression for m = 3.
(2m² + 5m - 7) / 2

Answer 1

Answer:

1) x = 15

x - 9

15 - 9

Answer = 6

2) x = 3 y = 5

3x + 2y

3*(3) + 2*(5)

9 + 10

Answer = 19

3) s = 5

s² + 7s - 2

(5)² + 7*(5) - 2

25 + 35 - 2

60 - 2

Answer = 58

5) x = 3 y = 5

x² + y²

(3)² + (5)²

9 + 25

Answer = 34
