The red line is 180 degrees. So the arcs on top of the circle all equal up to 180 degrees. the number 72 doesn't really matter cause you're trying to find out the angle of DCE which is on the other side of the circle. So you gotta find the arc length of DE which is 68 because 180-112=68. So to find the angle, you have to divide the opposite arc length by two, which is 34.

ANSWER: A. 34. you're welcomee!!

Simplify the polynomial. Then find its value for the given value of the variable.

zloy xaker [14]

Answer:

simplified: xy²
value: 4

Step-by-step explanation:

The polynomial is simplified by combining like terms. Like terms are identified more easily if the variables in each term are written in the same order. We usually like to use alphabetical order. Two of the like terms have opposite coefficients, so they cancel. The result is ...

(3 1/2 -2 1/2)xy² +(-2 4/5 +2 4/5)x²y

= xy² . . . . simplified expression

For x = 1, y = -2, the value of the expression is ...

(1)(-2)² = 4
