15 + 10 + 16 = 41
for the unshaded area
subtract the area of the whole rectangle shaded.
whole rectangle is
16(8) = area of 128
unshaded = 128 - 41 = 87
so your answers are
41, and 87
For #1 the answer is A because if lines parallel then exterior angles congruent.
Answer:
a
Step-by-step explanation:
Since it’s in percents, put the percent over 100 as a fraction and simplify them. For percents that aren’t given, add the rest and subtract it from 100 and then place it as a fraction over 100

Answer: x = -1</h3>
Explanation:
The given quadratic is in the form y = ax^2 + bx + c
We have a = 1, b = 2, c = 2
This then leads to
h = -b/(2a)
h = -2/(2*1)
h = -1
This is the x coordinate of the vertex (h,k)
The axis of symmetry is the vertical line passing through the vertex. So it must share the x value in question.
Meaning the axis of symmetry is x = -1. Every point on this vertical line has an x coordinate of -1. This line of symmetry splits the parabola into two equal mirrored halves.
I recommend using a graphing tool like Desmos to visually confirm the answer.
