Answer:
51
Step-by-step explanation:
11+(-7)^2-9 - original
11+49-9 - square the -7, since its in brackets the negative applies too and a negative x a negative = positive, so it ends up as 7x7+49
60-9 - add both positives 11+49=60
51 - subtract 9 from 60, 60-9=51
It would be 14 for the perimeter
Answer:
15x 12y=489
Step-by-step explanation:
In the problem it says that x is the number of adult shirts which 15 and y is the number for a youth shirt. So it would be 15x 12y. Hope this helped! :D
2 = 47 degrees
1 = 133 degrees
3 = 133 degrees
2 is opposite of x, so the angles are equal. Angle 2 is 47 degrees
A straight line is 180 degrees. Subtract 47 from 180 to get 133. Therefore, Angle 1 is 133 degrees. Because Angle 3 is opposite of Angle 1, it has the same angle as Angle 1. So Angle 3 is 133 degrees.
