L = 3 + 2w
119 = w × ( 3 + 2w )
119 = 3w + 2w^2
2w^2 + 3w - 119 = 0
( w - 7 ) ( 2w + 11 ) = 0
w = 7
x = w
x = 7
Answer:
z=-75/17
Step-by-step explanation:
Expand this equation:
-4z+8+4=-21z-63
-4z+21z=-63-8-4
17z=-75
z=-75/17
Answer:
69
Step-by-step explanation:
as , 77+x = 146(external angle) , so x = 146 - 77
so x = 69
Answer:
the second one on the top right
