He can make 2 batches of cookies. I'm not sure about the leftover cups because you wrote sugar twice
-3x^2 + 12x -6
a = -3
b = 12
We calculate the vertex "x" value with this formula:
(vertex "x value") = -b / (2*a)
(vertex "x value") = -12 / -6
The vertex "x" value equals the axis of symmetry value.
The axis of symmetry is at x = 2.

Answer
The statment true about the image be
The measure of ∠TRU is 72° .
Reason
As shown in the image
∠QRU = 90°
∠ TRQ = 18°
Now ∠QRU be written as the sum of the ∠ TRQ and ∠TRU .
Thus it becomes
∠QRU = ∠ TRQ + ∠TRU
put the value ∠QRU and ∠ TRQ
we get
90° = 18 ° + ∠TRU
Solving the above
∠TRU = 90° - 18°
∠TRU = 72 °
Therefore the measure of ∠TRU is 72 °.
Hence proved
