Answer:
y = -2x^2(x - 3)
Step-by-step explanation:
<em><u>Preliminary Remark</u></em>
If a cubic is tangent to the x axis at 0,0
Then the equation must be related to y = a*x^2(x - h)
<em><u>(3,0)</u></em>
If the cubic goes through the point (3,0), then the equation will become
0 = a*3^2(3 - h)
0 = 9a (3 - h)
0 = 27a - 9ah
from which h = 3
<em><u>From the second point, we get</u></em>
4 = ax^2(x - 3)
4 = a(1)^2(1 - 3)
4 = a(-2)
a = 4 / - 2
a = -2
<em><u>Answer</u></em>
y = -2x^2(x - 3)
We know that:
Area= length*width
Plug in the stuff you know.
35= length(tall)*5
Divide both sides by 5.
7= length
The photo is 7 inches tall.
I hope this helps!

Yes, because it still have 3 sides.
Fill in the blank with equation.
An equation is nearly the same thing as an expression. However, the dofference is that equations have an = sign while expression do not.
