It’s A
As it says in the answer, you usually add / subtract the exponents when needed.
Answer:
7a(3-a)
Step-by-step explanation:
21a-7a²
there GCF is 7
and has the same variable a
=7a(3-a)
Answer:
5. D: (-4,3] R: (5,-4] 7. D: (-1, 4] R: ( 5, -5]
Step-by-step explanation:
The domain is the point most to the left, and the point most to the right on the graph. The range is the point highest up and the point lowest down on the graph. You make a parentheses when the circle is hollow, but use a bracket when the circle is filled.

Answer:
50.031 watts
Step-by-step explanation:
Formula
Power = Force * distance / time
The units are critical
distance = meters
time = seconds
force = newtons = kg * m / s^2
Solution
F = m * a
a = 9.81
m = 102 kg
F = 102 * 9.81 = 1000.62 Newtons
T = minute = 60 sec/min * 1 min
T = 60 seconds
d = 3 meters
Power = 1000.62 * 3 / 60
Power = 50.031
