(x + 1) x (x - 4). When you check it you will get your original expression.
2(4x-3)-7(x+1) first distribute
8x-6-7x+7 then combine the x's
<u>x+13 </u>
The 3rd illustration from the left would be your answer.. You can see the quadrilateral is a trapezoid having the one pair of parallel sides constructed.
From 100 to 80 is 8/10, so the recursive formula is
an=a(n-1)*1/8
or
an= a1*1/8(n-1)
an=a1*(n-1)/8
V=l*w*h
V= 15*8*3
V= 120*3
V= 360
The pool will hold 360 cubic meters.
