Answer: (1, -2, -6); sqrt41
Step-by-step explanation:
9) Separate the polygon into 2 shapes (a rectangle and triangle). Then plug in the formula for those 2 shapes separately and add the 2 areas.
First, the triangle's area = bh x 1/2 or bh/2.
b=5 and h=5, so 5x5/2 or 25/2 = 12.5.
Next, solve the area for the rectangle(lw=A). l=5 and 2=8, so 5x8=40.
Add 40 +12.5 = 52.5cm^2 (always include units).
10) It is similar to the last problem. You will separate the polygon into 2 shapes (a circle and a square), but this time you will subtract the area of the sector formed from the circle (draw a dotted line where the circle would be formed in the square).
So, the area of the square is 2x2=4ft^2.
area of a circle is (pi)r2 or (pi)2^2= 4pi or about 12.5ft^2.
4+12.5 = 16.5 ft^2.
Now, the area of the sector must be subtracted from the combination of the 2 areas found above.
The area of a sector is 2(pi)r x (C/360).
The angle is given as 90°, the radius is 2 ft. Now plug these into the equation.
2(pi)(2)x(90/360) = 3.14ft^2.
16.5-3.14= 13.4 ft^2.

From the way the question is worded, I think there's a list of choices
that's supposed to go along with it, and I'm sad and disappointed that
you decided not to share them. But heck, ANYbody can pick the right
answer from a list of choices, but it takes a real Brainly to pick the right
answer from a list of no suggestions at all.
(3x - 2) + (x² - 5) + (2x + 7) =
3x - 2 + x² - 5 + 2x + 7 =
(x²) + (3x + 2x) + (-2 - 5 + 7) =
<em>x² + 5x </em>miles
or <em>x (x + 5)</em> miles (same thing)
