Apan balance shows x+2=10. if you add 5 units to one side, can you balance the scale by adding x units to the other side. explain?

No    10-2 =8   x=8
8+8 = 16 +2 = 18    if you add 5 units to the other side it would equal 15
18 and 15 are different numbers    so no

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.

I'm not sure but i think it's 1670km/h
