Tomas learned that the product of the polynomials (a + b)(a2 – ab + b2) was a special pattern that would result in a sum of cubes, a3 + b3. his teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if a = 2x and b = 1. which product should tomas choose? a) (2x + 1)(2x2 + 2x – 1) b) (2x + 1)(4x3 + 2x – 1) c) (2x + 1)(4x2 – 2x + 1) d) (2x + 1)(2x2 – 2x + 1)

(a + b) * (a^2 - a*b + b^2)

= (2x + (1)) * ((2x)^2 - (2x)*(1) + (1)^2)

C) (2x + 1) * (4x^2 - 2x + 1)

we know that

we are given

now, we can plug this in formula

and we get

now, we can simplify it

and we get

so,

option-C.......Answer

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
