Answer:
-20
Step-by-step explanation:
(r + b − g)(b + g)
we have fom statement:
r = 9
b = 5
g= −6
so we have:
(r + b − g)(b + g)= (9+5-(-6))*(5+(-6))
(r + b − g)(b + g)= (14+6)*(-1)
(r + b − g)(b + g)= -20
Answer:
The discriminant is the part under the square root in the quadratic formula, b²-4ac. If it is more than 0, the equation has two real solutions. If it's less than 0, there are no solutions. If it's equal to 0, there is one solution.

Answer:
The median is -8°F
Step-by-step explanation:
Attached Table.
The median is the "middle" value from all the numbers arranged from least to greatest.
Looking at the table, we need to arrange the numbers (first week numbers) from least to greatest.
-31, -29, -9, -8, 3, 4, 6
There are 7 numbers and the middle number is the 4th one, which is -8
The median is -8°F
The answer is: [C]: "Astrologers do not use the scientific method."

The answer is g = 6w.
since the number of grey pigeons is 6 times the white pigeons, it means the white pigeons are being multiplied to find the number of grey pigeons
