Answer:
I was unclear if you needed this solved in vertex or standard form, so I gave you both.
Vertex form: 
Standard form: 
Step-by-step explanation:
This is a quadratic equation. In order to solve this problem, you will need these equations:
Vertex form: 
Standard form: 
Starting with vertex form:
The vertex is (4, -1). When putting this into your equation, substitute the "x" value for h, and substitute the "y" value for k.

You can disregard the "a" for this particular problem because it is equal to 1.
Standard form:
Now that you have vertex form, you can expand it into standard form.

Use the FOIL method to multiply (x - 4)(x - 4).
This will equal
.
Keep in mind that you still have a -1 from your original equation to take into account. Once you subtract 1, this will leave you with:

Answer:
x= -2
Step-by-step explanation:
-16x-8=24
−16x−8=24
−16×=32
answer x=-2
1. add 8 to both sides
2.simplify
Answer:
13r²(2rs + 4r³ - 3s⁴)
Step-by-step explanation:
In equation 26r³s + 52r⁵ - 39r²s⁴;
The GCF of 26, 52, and 39 = 13
The GCF of r³, r⁵ and r² = r²
The GCF of s, (no "s"), and s⁴ = no "s" (Since one of the number doesn't have "s")
Now we can factor out 13r² from all three expressions;
26r³s + 52r⁵ - 39r²s⁴
=> <em>13r²(2rs) + 13r²(4r³) - 13r²(3s⁴)</em>
To factor it all together;
<u>13r²(2rs + 4r³ - 3s⁴)</u>
Hope this helps!
Answer:
2827.433
Step-by-step explanation:
First start with the volume of a sphere and use the given volume to solve for the radius r.
So the radius of this sphere is 15 inches.
Now we use this radius to find the surface area
And then you get 2827.433
X = 79/16, D : 4.9375 :) hope this helps uu!
