Find the value of mp - 2p when m = -5 and p = - 8

• 56

• 50

• -24

• -56

Answer explanation

-5 x -8 = 40 then -2 x (-8) =16 finally 40 + 16 = 56

Evaluate 5g - j if g =24 and j = -72

• -43

• 452

• 192

• 48

Answer explanation

5 x 24 = 120 then 120 -72 = 48

Evaluate w² - y if w = 9 and y = -17

• 64

• 98

• 1

• 35

Answer explanation

9 squared is 9 x 9 = 81; 81 - (-17) = 81 + 17 = 98 (remember minus a negative becomes a positive.)

Evaluate (y - x)³ if x = 15 ; y = 21

• 36

• 46,656

• 128

• 216

Answer explanation

21 - 15 = 6, then 6 x 6 x 6 = 216

Evaluate 6 + (r + s)² if r=13 ; s =2

• 21

• 32

• 231

• 225

Answer explanation

13 + 2 = 15; 15 squared is 15 x 15 = 225 then 225 + 6 = 231

16 = c +10

• c = 16

• 26 = c

• 6 = c

• c = 160
