Answer the question it fill in the blank for 20pt

The equation they're talking about is f(x) = a(x - h)² + k, by the way.

A parabola is ... a quadratic equation. The vertex is the max ...  

The value of h moves. .. horizontally ... the value of k moves ... vertically.  

The value of a determines ... upward ... If a is greater than zero, ... upward.  If a is less than zero, ... downward.

|a|>1 is narrow,  |a|<1 is wide

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
