The answer is the third one need any more help let me know
Answer:
Step-by-step explanation:
p^2-8p-9
factor out the trinomial
(p-9)(p+1)
Therefore, she's incorrect. Because (p-1)(p+9)=p^2-p+9p-9=p^2+8p-9 and that's different from p^2-8p-9.
4x-2+1=3x+5
Subtract 3x from both sides
x-2+1=5
Same as
x-1=5
Add 1 to both sides
x=6
ANSWER
111.3 square units.
EXPLANATION
The formula for calculating the area of a triangle is.

Let us the side of the triangle with side 12 units to be the base of the triangle.
Then the height of the triangle can be determined from the diagram using trigonometry.



We now plug in the values in to the formula to obtain,


See graph
Step-by-step explanation:
Y varies directly as cube root of x is written as
y = k³√x
where k is the constant of proportionality
<h2>A).</h2>
when y = 3
x = 27
We have
![3 = k \sqrt[3]{27}](https://tex.z-dn.net/?f=3%20%3D%20k%20%5Csqrt%5B3%5D%7B27%7D%20)
But ³√27 = 3
That's
3 = 3k
Divide both sides by 3
k = 1
<h3>The value of the constant is 1</h3>
<h2>B).</h2>
The value of the relationship is
<h2>
![y = \sqrt[3]{x}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Csqrt%5B3%5D%7Bx%7D%20)
</h2>
<h2>C).</h2>
When x = 8
We have
<h2>
![y = \sqrt[3]{8}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Csqrt%5B3%5D%7B8%7D%20)
</h2>
<h3>y = 2</h3>
Hope this helps you
