Answer
-2v+8 (1+2v)=-90 then V = -7
Step-by-step explanation:
-2v + 8 x (1 + 2v) = -90
-2v + 8 + 16v = -90
14v + 8 = -90
14v = -98
V = -98/14
V= -7
Hope this helps ;)
Answer:
v=2-2root7, v=2+2root7
Step-by-step explanation:
-2v+8(1+2v)=-90
-2-4v^2+8+16v=-90
6-4v^2+16v=-90
-4v^2+16v=-96
v=2-2root7, v=2+2root7
