13% of the u. s. population (2009 estimate) is african-american. if the u. s. population is 307 million, how many african-americans live in the united states?

307,000,000 divided by 100 x 13 = (39910000)

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

if you was gonna solve for a, a is a   < -12
