Answer:

C. y = x2 + 8x + 12

Step-by-step explanation:

To find x intercept/zero, substitute y = 0

0 = x^2 + 8x + 12

x^2 += 8x + 12 = 0

x^2 + 8x + 12 = 0

Solve the quadratic equation

  • ax^2 + bx + c = 0 using x = -b±\sqrt{b^2 -4ac / 2a
  • x = -8±\sqrt{8^2 -4(1)(12) / 2(1)

x = -8±\sqrt{8^2 -4(12) / 2(1)

any expression multiplied by 1 remains the same

x= -8±\sqrt{8^2 - 4(12) / 2(1)

Evaluate the power

8^2

write the exponentiation as a multiplication

8(8)

multiply the numbers

64

x = -8±\sqrt{64 - 4(12) / 2(1)

multiply the numbers

x = -8±\sqrt{64 - 48 / 2(1)

any expression multiplied by q remains the same

x = -8±\sqrt{64-48 /2

subtract the numbers

x = -8±\sqrt{16 / 2

calculate the square root

x= -8± 4 / 2

x= -8 + 4 / 2

x= -8 - 4 / 2

simplify the expression

x = -2

x = -8 - 4 / 2

x = -2

x = -6

final solutions are

x1 = -6, x 2 = -2

X + (2x + 40) + (3x – 50) = 15,002
Rufina [12.5K]
Hello there!

x + (2x + 40) + (3x - 50) = 15002

Remove the parentheses

x + 2x + 40 + 3x - 50 = 15002

Combine like terms

x + 2x + 3x + 40 - 50 = 15002

6x - 10 = 15002

6x = 15002 + 10

6x = 15012

x = 15012/6

x = 2502

List two real-world scenarios in which you would multiply a decimal by a decimal.
DedPeter [7]
It's obvious that every normal person has ten fingers. Since we have ten fingers, our numbering is based on multiples of ten which is called decimal. Can you imagine how life would be different if all human beings were born with eight fingers instead of ten? Maybe our numbering system would be based on multiples of eight. A numbering system based upon eight exists and is called octal. Octal numbering is used behind the scenes in computer systems.
