Answer:
-4, 11
Step-by-step explanation:
X-intercepts occur at y=0:
x^2-7x-44=0
(x-11)(x+4)0
so we have -4 and 11.
We have 13 total shapes and 7 of them meet the criteria, so the probability is:
<span>
</span>P(<span>Square or Triange) = </span>

<span>or about
0.3888.....
or
38.88%</span>
-13 -> 6 // 13+6 = difference of 19. 19/4 (days) = 4.75. The water level increased by 19' total and 4.75' each day
