I think the correct answer from the choices listed above is option A. The completely factored formed of the function xy^3 – (x^3)y would be xy (x+y) (x-y). It is factored as follows:
<span>xy^3 – x^3y
xy (y^2 - x^2)
xy (x+y) (x-y)

Answer:
Step-by-step explanation:
The central angle of the segment is 60 degrees. Line CD is the same length as the radius and there are 3 sides with the same length. The triangle so formed is equilateral and the apex angle is 60 degrees which is the central angle.
The measure of arc CD is 60 degrees.
Lets try to solve this problem using 2 equations, also,we will have bananas=b and pears =p
5b+3p= $3.80
2b+4p= $3.20 i will divide this equation by 2 and get
b+2p= $ 1.60 we subtract 2p from both side so i can find the cost for 1 banana
b+2p-2p=1.60-2p
b= $1.60-2p
I will replace the b in the first equation now,
5(1.60-2p)+3p=$3.80
8-10p+3p=3.80 solving for p
8-7p=3.80 we subtract 8 from both sides
-7p=-8+3.80
-7p=-4.20 we multiply both sides by (-1)
7p=4.20 we divide now both sides by 7
p=0.60 a pear cost 0.60 cents
a banana is b=1.60-2p, b=0.40 cents
Answer:
<em>x = 49°</em>
Step-by-step explanation:
<u>Angles in a Triangle</u>
The sum of the internal angles in any triangle adds up to 180°.
The figure shows a triangle that includes two angles with the same tick mark. This means they are congruent, i.e. they measure the same.
The larger triangle has three defined angles: 43°, 39°, and 2x. Since the sum of them is 180°:
43° + 39° + 2x = 180°
Operating:
82° + 2x = 180°
Subtracting 82°:
2x = 180° - 82° = 98°
x = 98°/2 = 49°
x = 49°
