Answer:
a - 3.5x
b - 3.5 centimeters per minute
c - this means that in six minutes the water level will be at 21 cm
Step-by-step explanation:
<u>L</u><u>a</u><u>w</u><u> </u><u>o</u><u>f</u><u> </u><u>E</u><u>x</u><u>p</u><u>o</u><u>n</u><u>e</u><u>n</u><u>t</u>
Compare the terms.
Therefore, a = -2 and n = 3. From the law of exponent above, we receive:
<u>E</u><u>x</u><u>p</u><u>o</u><u>n</u><u>e</u><u>n</u><u>t</u><u> </u><u>D</u><u>e</u><u>f</u><u>.</u> (For cubic)
Factor (-2)^3 out.
(-2) • (-2) = 4 | Negative × Negative = Positive.
4 • (-2) = -8 | Negative Multiply Positive = Negative.
If either denominator or numerator is in negative, it is the best to write in the middle or between numerator and denominators.
Hence,
The answer is - 1 / 8
