Ineed ! i will mark brainliest, , and rate! . a circular window is surrounded by a circular frame. the radius of the window is z − 5 and the radius of the full circle formed by the frame is z + 5. write a polynomial that represents the area of just the frame itself, not including the space covered by the window.(the area of a circle is given by a = πr 2, where r represents the radius of the circle.) answer choices: -20 pi z 20 pi z 20 pi z+50 50

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
