A) it represents trough fill rate. It basically states after 8 minutes, the water level raised 28 cm.
B) for every 1 minute of pouring, the water level rises 3.5 centimeters.
C) if you look at those points as proportions
6/21 = 1/3.5
Or 8/28 = 1/3.5
They both can be proportionate.
<h2>Steps:</h2>
So firstly, I will be factoring by grouping. For this, factor x⁶ - 9x⁴ and -x² + 9 separately. Make sure that they have the same quantity on the inside of the parentheses:

Now, you can rewrite the equation as:

However, it's not completely factored. Next, we will apply the formula for the difference of squares, which is
. In this case:

Next, we will apply the difference of squares once more with the second factor as such:

<h2>Answer:</h2>
<u>The factored form of this equation is:
</u>
Answer:
-x^2 +8x -6
Step-by-step explanation:
Distribute the minus sign and collect terms.
(3x -8) -(x^2 -5x -2)
= 3x -8 -x^2 +5x +2
= -x^2 +8x -6
Answer:
706.4ft²
Step-by-step explanation:
This is a prism with a trapezoid base. The total area includes:
1) 2 trapezoids (bases):
A1=2×(19+5)×12.1/2=24×12.1=290.4ft²
2) side area:
A2=base perimeter×prism height=
(19+5+14+14)×8=(24+28)×8=52×8=416ft²
So total area is A1+A2
A=290.4+416=706.4ft²
4,6,8,10,12
Hope this helps!
