Answer:the answer to this question is C (16,12)
Step-by-step explanation:
Step-by-step explanation:
2x³ + 14x² + 4x + 28
2(x³) + 2(7x²) + 2(2x) + 2(14)
2(x³ + 7x² + 2x + 14)
2(x²(x) + x²(7) + 2(x) + 2(7))
2(x²(x + 7) + 2(x + 7))
2(x² + 2)(x + 7)
The answer is C.
Let's focus on the given equation. The C represents the cost, while the x must be the number of tacos, which is what we're solving for. Since we're given the boundary that C must be 300, then the solution would be:
300 = x² - 40x + 610
x² - 40x + 310 = 0
Apply the quadratic formula where a = 1, b = -40 and c = 310. The roots of x are:
x = 29.49≈30
x = 10.51≈11
<em>Thus, she needs to sell either 30 or 11 tacos.</em>
Step 1: Distribute
5x + 10 - 3x > 7 - 4x + 12
Step 2: Combine like terms
2x + 10 > -4x + 19
Step 3: Move all variable terms to one side, and all constants to the other
6x + 10 > 19
6x > 9
Step 4: Divide
x > 9 / 6
x > 1.5
Hope this helps!
