Anna wants to factor the polynomial p(x)=5x^4+40x. She knows that the sum of cubes formula is a^3+b^3=(a+b)(a^2−ab+b^2).

Answer:

Part A: Option 2, A: Anna’s answer is incorrect. She correctly factored out 5x, but incorrectly identified a and b, so her answer cannot be correct.

Part B: Option 3, B: 5x(x+2)(x^2−2x+4)

Step-by-step explanation:

p(x) = 5x^4 + 40x

p(x) = 5x(x^3 + 8)

p(x) = 5x(x + 2)(x^2 - 2x + 4)

Part A: Option 2, A: Anna’s answer is incorrect. She correctly factored out 5x, but incorrectly identified a and b, so her answer cannot be correct.

Part B: Option 3, B: 5x(x+2)(x^2−2x+4)

We know: The total number of tickets is 35. Another way of saying this is the number of adults plus the number of children equals 35. i.e.:

$Adults+Children=35$

Using the symbols provided we can write this is as:

$a+c=35$

We also know: The total money collected is $75. We know that $6 was collected for every adult or $6a$ and $1 for every child or $1c$ . i.e.:

$(SixDollars \times Adults)+(OneDollar \ times Children)= $70$

Using the symbols provided and adding it all up we can write this is as:

$6a+1c=70$

Equation 1: $a+c=35$
Equation 2: $6a+c=70$
