14) The cube root of 64 = 4, and the cube root of 27 = 3.
(4x)³ + (3)³
a = 4x, b = 3
(4x+3)(4x²-12x+9)
15) The cube root of 8 = 2, and the cube root of 125 = 5
So (2x)³ - (5)³
a = 2x, b = 5
(2x-5)(2x²+10x+25)
Answer:
10 pounds is more
Step-by-step explanation:
Answer:
a) Unit price :
- 12 cupcakes for $29 = $2.42
- 50 cupcakes for $129 = $2.58
Reasoning:
- 12 cupcakes for $29 = $29 ÷ 12 cupcakes which gives 2.416666667 and if rounded off gives you $2.42.
- 50 cupcakes for $129 = $2.58 accurately.
b) 12 cupcakes for $29 gives the lowest unit price as $2.42 is less than $2.58.
