If you draw the figure, RT and SQ turn out to be the diagonals of the rectangle since diagonals of a rectangle are equal, so RT = SQ ==> 4x - 16 = x + 5 ==> 4x - x = 5 + 16 ==> x = 21/3 = 7
Take you the common factors. those are 2 and x. So if you divided 2x^2 by 2x you end with only one x. and if you divided 4x by 2x you end with 2. The final answer should look like 2x(x+2)=2x^2+4x
That 's easy!!! (x-h) ²+(x-k) ²=r²
(h, k) is the coordinate of centra
r is radius
and(x-h) ²+(x-k) ²=r² is written in standard form, which u can directly get the value of center and radius
so for ur question center is (7 and -4)
radius is 7
72000/12=6000 12 pools of equal volume, both start and end are in gallons so it's just basic division.
