(moment/area) integral of x(dA)/itegral of dA for the x coordinate (integral of y(dA)/itegral of dA for the y coordinate
2x5=9
I assume that the question means 4x-7=2x+5. In that case, the answer x would equal 6.
You multiply the bases, for example, 23 x 53 = 103.The general rule is for real numbers ( but it works for others as well) a and b(ab)n =an bnI think it helps to see why this is true. Look at the example given23 is 2x2x253 is 5x5x5If we multiply these we have2x2x2x5x5x5 which is three 2's and three 5's.Now rearrange them which we can do because of the commutative property ofmultiplication and pair up each 2 with a 5 and here is what you have:(2x5)(2x5)(2x5)this is (2x5)3
