The x value of the vertex in
ax^2+bx+c is -b/2a
y value is just sub for x
3x^2-6x+5
x value of vertex is -(-6)/(2*3)=6/6=1
sub back
y=3(1)^2-6(1)+5
y=3(1)-6+5
y=3-1
y=2
vertex is (1,2)
Answer:
<h2>
N=-2</h2>
Step-by-step explanation:
Step 1: Subtract 1 from both sides.
2n+1−1=−3−1
2n=−4
Step 2: Divide both sides by 2.
2n/2=−4/2
n=−2

So all you have to do is divide 166 by 7
would be your final answer. 166/7 is a repeating decimal so I left it in fraction form.
D. 147 square units is your answer
The answer is 19.
The length would be 342 divided 18. The formula for area of a rectangle is length times width equals area, so area divided by width would be the length.
