Answer:

⇒ 4(x-2)(2x+1)

Step-by-step explanation:

1) Common factor

⇒ 8x^2-12x-8\\

⇒ 4(2x^2-3x-2)

2) Use the sum-product pattern

⇒ 4(2x^2-3x-2)

⇒ 4(2x^2+x-4x-2)

3) Common factor from the two pairs

⇒ 4(2x^2+x-4x-2)

⇒ 4(x(2x+1)-2(2x+1))

4) Rewrite in factored form

⇒ 4(x(2x+1)-2(2x+1))

⇒ 4(x-2)(2x+1)

kiyo bought a pizza for 12.75 and four medium drinks to Pauli’s pizza. Define a variable and write an expression to represent th
Stels [109]

The total cost, if one drink costs $3 is $27.75

  • Let the cost of a pizza be x

  • Let the cost of a drink be y

If kiyo bought a pizza for 12.75 and four medium drinks to Pauli’s pizza, this expressed as x + 4y

Since a pizza costs $12.75, hence x = $12.75

The function becomes 12.75 + 5y

f(y) = 12.75 + 5y

To get the total cost if one drink costs $3, hence;

f(3) = 12.75 + 5(3)

f(3) = 12.75 + 15

f(3) = 27.75

Hene the total cost, if one drink costs $3 is $27.75
