The vertex of this parabola is at (2 -4) when the y-value is -3 the x-value is -3 what is the coefficient of the squared term.?

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

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
