Ok so this is so confusing The volume of water in a rectangular swimming pool can be modeled by the polynomial 2x3 _ 9x2 + 7x +
6. If the depth of the pool is given by the polynomial 2x + 1, what polynomials express the length and width of the pool? Why couldn't they just give me the volume?
The volume formula is V= l x L x H, l=width, L=Length, H= Depth, so 2x3 _ 9x2 + 7x + 6 = l x L x (2x + 1), because H=(2x + 1), so l x L= (2x3 _ 9x2 + 7x + 6 )/ (2x + 1) = (2x3 _ 9x2 + 7x + 6 ) X [1/(2x + 1)] case1: l= (2x3 _ 9x2 + 7x + 6 ) or L= 1/(2x + 1), case2: L= (2x3 _ 9x2 + 7x + 6 ) or l= 1/(2x + 1) the why question: perhaps there is similarity of value between volume and l, or volume and L
The answer should be 31, if I’m doing this correctly. 6(3)2-5 (multiply 6 and 3, you get 18) 18(2)-5 (multiply 18 and 2, you get 36) 36-5 (subtract 36 and 5) 31
