Question

Evaluate 3 + (a + 4)(8 - b) when a = 5 and b = 6

Answer 1

2(s+t)^3 - 6 when s=3 and t=2

Answer 2

12+3

Answer 3

First, substitute the values of a and b into the expression:

3 + (5 + 4)(8 - 6)
= 3 + (9)(2)
= 3 + 18
= 21

Therefore, 3 + (a + 4)(8 - b) evaluates to 21 when a = 5 and b = 6.

Answer 4

First, substitute the values of s and t into the expression:

2(3 + 2)^3 - 6
= 2(5)^3 - 6
= 2(125) - 6
= 250 - 6
= 244

Therefore, 2(s+t)^3 - 6 evaluates to 244 when s = 3 and t = 2.

Answer 5

12 + 3 = 15
