f(x) = 4x - x² - 2x
Vertex form of a parabola: y = a(x - h)² + k where (h, k) is the vertex of this parabola
y = a.(x - h)² + k
y = -1.(x - h)² + k
Let's factor:
f(x) = -x² - 2x + 4
f(x) = -(x + 1)² + 1 + 4
f(x) = -(x + 1)² + 5
So we don't even need to find the vertex, we can just factor.
Answer:
2x+3
Step-by-step explanation:
The area of the rectangle can be found by length x width. The area is 32x+48 and the length is 16. Factor the area 32x+48 using 16 as the GCF: 16(2x+3). This means the width is 2x+3.
Answer:

Hope this helps. :)
I think it’s (2,-1) i hope it’s right!!
Answer:
Im pretty sure the answer is 6
Step-by-step explanation:
Leave the 24 aside for a sec. Focus on the 6÷2 and 4÷2. 6 divided by 2 is 3. And 4 divided by 2 is 2. So now its 24÷3= 8
8-2=6
