(9+radical -4)-(5+ radical -16)

16

Step-by-step explanation:

(9 + radical - 4) - (5 + radical - 16)

9 + radical - 4 - 5 - radical + 16

9 - 4 - 5 + 16 + radical - radical

= 16

x = 8

y = 14

Step-by-step explanation:

2x + 6 = 4x - 10 (Corresponding angles so they're equal)

2x - 4x = -10 - 6

-2x = -16

x = 8

2x + 6 + 13y - 24 = 180 (Supplementary angles so they add up to 180)

2(8) + 6 + 13y - 24 = 180

16 + 6 + 13y - 24 = 180

13y - 2 = 180

13y = 182

y = 14
