We know that
<span>the vertex form of the equation is
y=a(x-h)</span>²+k
we have
y = 7x² + 14x +4
y=7(x² + 2x) +4
y=7(x² + 2x+1-1) +4
y=7(x² + 2x+1) +4-7
y=7(x+1)²-3
the answer is
y=7(x+1)²-3
David drove at about 59 mph!
No because 9/1,000 in decimals would be 0.009 because if the number was a 3 number then it would go in the tenths
The cross section will be rectangle. You can make a cylinder out of a dough and try to cut it. You will see the cross section is rectangle.
