Answer:
x=2
Step-by-step explanation:
28−(3x+4)=2(x+6)+x
We need to use the distributive property for the right side.
28−3x−4=(2)(x)+(2)(6)+x)
28−3x−4=2x+2+x
−3x+24=3x+12
From here we need to subtract 3x from both side.
−3x+24−3x=3x+12−3x
6x+24=12
Transfer +24 on the right side.
6x=12−24
6x=−12
Finally, divide both sides by −6
6x/-6 = -12/-6
x=2

i think? i may have not understood the picture correctly, so if this is wrong i apologise
The vertex form of a quadratic equation is y = n(x − h)2 + k, where (h, k) gives the coordinates of the vertex of the parabola in the xy-plane and the sign of the constant n determines whether the parabola opens upward or downward.
If n is negative, the parabola opens downward and the vertex is the maximum.
The given equation has the values h = 3, k = a, and n = −1.
Therefore, the vertex of the parabola is (3, a) and the parabola opens downward.
Thus, the parabola’s maximum occurs at (3, a)
