F(x) = x² + x - 20 = x² + 5x - 4x - 20 = x(x + 5) - 4(x + 5) = (x + 5)(x - 4)
f(x) = 0 ⇔ (x + 5)(x - 4) = 0 ⇔ x + 5 = 0 or x - 4 = 0 ⇒ x = -5 or x = 4
Answer: C. x = -5 and x = 4.
Answer:
y = 17x - 55
Step-by-step explanation:
Convert the coordinates in point-slope form:
y + 4 = 17(x -3)
y + 4 = 17x - 51
Subtract 4 in both sides:
y = 17x - 55

500 milliliters x 4 = 2000
2000 +1000 = 2 Liters
The answer is 2 liters of milk
V = 70 ft<span>3
V=lwh so 5*2*7 = 70
