Answer:
No solutions
Step-by-step explanation:
The graph does not contact the x axis
There are no real answers for this reason.
The relation between the width and the length is :
l = 3w +4 -- eqn (1) Perimeter = 56 » 2w + 2l = 56 Dividing through by 2 gives; w + l = 28 w = 28 - l -- eqn(2) Substitute eqn (2) in eqn (1) » l = 3(28-l) +4
Expanding bracket gives; l = 84 - 3l +4
Grouping like terms , we have; l + 3l = 84+4 4l = 88
l = 88/4 l = 22
The length of the rectangle is 22 units.

Let the ceilings be <em>a</em><em> </em><em>&</em><em> </em><em>b</em>
and the distance from one corner of the ceiling to the opposite be <em>c</em>
<em>then </em><em>using</em><em> </em><em>Pythagoras</em><em> theorem</em>
hence ,c .°. the distance from one corner of the ceiling to the opposite is<em> </em><em>2</em><em>0</em>
The question asks you to find the total amount of rain after each hour, and has given you the ratio of 1.5 cm of rain in an hour. Therefore to find the rest, you’ll need to multiply the number of hours by the amount of rain in an hour:
2hrs - 3 cm
3hrs - 4.5 cm
4hrs - 6 cm
5hrs - 7.5 cm
I hope this helps and that I’m right! Good luck!! :)
