Question

The area of a rectangular swimming pool is 10x2 – 19x – 15. The length of the pool is 5x + 3. What is the width of the pool? (1 point)
2x – 18
2x – 5
5x – 5
5x – 22

Answer 1

this is a round about way of asking you to factor
\[10x^2-19x-15=(5x+3)(\text{something)}\] so your job is to figure out which of these factors work

Answer 2

we do this by thinking
you have
\[(5x+3)(ax+b)=10x^2-19x-15\] and the only way this will work is if
\[5a=10\] so
\[a=2\] and also if
\[3b=-15\] so
\[b=-5\]

Answer 3

makes the answer
\[2x-5\]
hope steps are clear

Answer 4

wouldnt this pool just amount to a rectangular puddle?

Answer 5

lol last pool was given as 10 cm by 4 cm
maybe for your big toe?
