I can’t see a picture of the grid
The inside angle for B, which is labeled x is the same as the outside angle of D which is labeled as 72, so we know x = 72.
In a parallelogram two angles next to each other equal 180, so angle A and angle B equal 180.
We know B = 72, so A = 180-72 = 108
Angle A is divided in 2 by angle y, so y = 108/2 = 54
Answers: x = 72
Y = 54

Compare the terms.

Therefore, a = -2 and n = 3. From the law of exponent above, we receive:

<u>E</u><u>x</u><u>p</u><u>o</u><u>n</u><u>e</u><u>n</u><u>t</u><u> </u><u>D</u><u>e</u><u>f</u><u>.</u> (For cubic)

Factor (-2)^3 out.

(-2) • (-2) = 4 | Negative × Negative = Positive.

4 • (-2) = -8 | Negative Multiply Positive = Negative.

If either denominator or numerator is in negative, it is the best to write in the middle or between numerator and denominators.
Hence,

The answer is - 1 / 8
3:5 my answer has to be 20 characters so im just typing the rest of this to answer your question.
If u subtract 6-9 u would get a -3 because the 9 is bigger than the 6 so thats how you get a -3.
