Use the distributive property to expand the expression.

−13x − (3y − z) + 5

a)
−13x − 3y + z + 5

b)
−13x + 3y − z − 5

c)
−13x − 3y + z − 5
eliminate

d)
−13x − 3y − z − 5

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
