first one because you’re multiplying everything inside the parenthesis by 3
Answer:
area of parllelogram=base×height=(4+8)×7=12×7=

Answer:
vertex (5,2)
axis of symmetry: x=5
Step-by-step explanation:
vertex (h,k)
y = a(x - h)² + k
f(x)=(x-5)²+2 a = 1 h = 5 k = 2
vertex (5 , 2)
The axis of symmetry always passes through the vertex of the parabola. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
x = 5
By the fundamental theorem of algebra, we can write

Expanding the right hand side, we get

We want
to be an integer, which means
must also be integers. This means
must be factors of 10. There are several possibilities:


So there are 4 possible values for
: -11, -7, 7, and 11.
