Answer:
x = -1
Step-by-step explanation:
x = x2 -5x = 3
-5x + 2x = -3x
x = 1
(-1)2 - 5(-1) = 3
-2 + 5 = 3
2/6. because there are 6 part of the square and there are 2 that are shaped red.
Answer:
7
Step-by-step explanation:

Answer:
w= 12
Step-by-step explanation:
2w=24

w= 12
Answer:
Option (C).
Step-by-step explanation:
Table represents the population of the owls in a park in different years and the quadratic regression equation that models the data of the table is,
y = -1.34x² + 10.75x - 11.3
Where y = number of owls
x = year
y = -1.34(9)² + 10.75(9) - 11.3
= -108.54 + 96.75 - 11.3
= -23.09
≈ -23
But Number of owls can't be negative.
Therefore, Option C. will be the answer.
