so, they already used 4,885.78 this month, but whatever all five family members can use total for a month is 7,250.50, so since they already used 4,885.78, they have left 7,250.50 - 4,885.78 = 2364.72.

<span>g(x) = x^2 + 4x + 3
y-intercept: let x=0. Then y=3. y-intercept is (0,3).
roots: set g(x) = 0 and solve for x. x=-1 and x=-3.
-4
axis of symmetry: find x = -b / (2a), which here is x = ----- = -2

There could be 2 possible shapes that could’ve been drawn.
A rectangle, or a square.
All of their angles are 90° angles, which are right angles.
Hope this helped!
