Answer:
196
Step-by-step explanation:
Answer: Hi The Answer would be 46.
Step-by-step explanation:
The height is 3.
The square centimeters show that the length and width multiplied resulted in the 30. (Centimeter times centimeter = square centimeter.) so you divide the 90 by 30 and the answer is 3.
Area=lw
Volume=lwh
Area given = 30
Volume given = 90
90=30h
H=3
The volume of the ethanol inside the tube can be obtained by dividing the mass of ethanol by the density. The volume is equal to 15.03 ml or 15.03 cm3. The volume of the tube is equal to pi d^2/4 * h where h is 15 cm. From this formula, the diameter is equal to 1.13 cm.
Starting with x=1, subtract 1 from each side,
(x-1)=0
Our polynomial will have multiplicity of 2 for this particular zero,
(x-1)(x-1)
and do similar with the x=-4, add 4 to each side,
(x+4)=0
So our final result is: (x-1)(x-1)(x+4)
Expand out the brackets if you need this in standard form.
