Step-by-step explanation:
-3x-5 becomes positive 15
-2x-1 becomes positive 2
6x6 is 36
7x-9 is -63
The actual speed of the plane with the wind:
v² = ( 150 + 50 · cos 45°)² + ( 50 · sin 45°)²
v² = ( 150 + 35.355 )² + 35.355²
v² = 34,356.467 + 1,249.976
v = √35,606.452
v = 188.7 mph
answer: positive
for example: -2 x -2 x -2 x-2
=4 x -2 x -2
=-8 x -2
=positive 16
