Which symbol replaces? to make the statement true? 2⋅18-18? 2⋅[28-3⋅ (2+4) ]

A. >

B. =

C. <

Which expression has a value greater than the given expression when a = 2?

2 (a + 6) A. 2a + a²

B. 4a + 8

First I would simplify each side in order to determine the symbol.

2 * 18 - 18? 2 * [28 - 3 (2 + 4) ] I will simplify the left side first. Multiply 2 and 18

36 - 18? 2 * [28 - 3 (2+4) ]

18? 2 * [28 - 3 (2 + 4) ] Now simplify the right side. Add 2 and 4

18? 2 * [28 - 3 (6) ] Next multiply 3 and 6

18? 2 * [28 - 18]

18? 2 * 10

18? 20

18 < 20 Your answer is C because 18 is less than 20

First find the value of the give expression

2 (a + 6) Since a = 2, plug in 2 for a

2 (2 + 6)

2 (8) = 16

A.) 2a + a² Plug in 2 for a

2 (2) + (2) ²

4 + 4 = 8

B.) 4a + 8 Plug in 2 for a

4 (2) + 8

8 + 8 = 16

Neither A or B have a value greater than the given expression
