Y=x²+8x+14
to make a square, if a is 1, add (half of b)²
in this case, a=1, b=8, half of 8 is 4
y=x²+8x+4²-4²+14
y=(x+4)²-16+14
y=(x+4)²-2
B is the answer.
another way to do it:
the vertex is at x=-b/2a=-8/2*1=-4
when x=-4, y=(-4)²+8(-4)+14=-2
so the equation is y=[x-(-4)]²-2, which is y=(x+4)²-2, the same answer B
Answer:
0.04
Step-by-step explanation:
1 over 25 is just like 1 divided by 25 so plug that into a calculator to get 0.04
