7. Use the Distributive Property to write each expression in expanded form. Use the AREA MODEL to SHOW YOUR WORK. A. 3(x + 7)
B. 5(5 − x)
C. 2(4x − 8)
D. (x + 4)(x + 2)

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

a negative exponent is translated as follows:

so, we have
