Answer:
144 degrees
Step-by-step explanation:
9x + 27 = 6x + 66
3x + 27 = 66
3x = 39
x = 13
9(13) + 27 = 144
The minimum y-value of the function for the parabolic equation is -13.
<h3>What is the vertex of a parabolic equation in quadratic form?</h3>
The vertex for an up-down facing parabola of the form y = ax² + bx + c is 
From the given equation:
y = x² + 8x + 3
The parameters for the parabola are:
a = 1, b = 8, c = 3


If we replace the value of
to find the minimum value of
value, we have:

Thus, the parabola vertex is (-4,-13). If a< 0, the vertex is a maximum value and If a>0, the vertex is a minimum value.

Answer:
Option D, 140 sq. units
Step-by-step explanation:
Area of the rectangle part, 11*5 = 55 sq. units
Area of the pentagon part (3.4*5)*5/2 = 42.5 sq. units
Total area,
55+2*42.5 sq. units (since there are two pentagons)
= 55+85 sq. units
= 140 sq. units
if the angles are the same, and side lengths are equally decreased or increased (depending if you are scaling up or down)
