Each person received 3 doughnuts, do 6 times 4 which is 24 and divide that among 8, its 3
Answer:
The area of half of the garden in square meters
Step-by-step explanation:
The opposite sides are supplementary
43+x=180
X=137
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.
