Answer:
Step-by-step explanation:
There is nothing you could put into the brackets that will give you a negative answer. We should just graph this to see if that is true or not. Graphs are the last word in this kind of question.
See below.
The graph is the first part: y = |5x +7|
It is the red graph.
The second line of interest is y = - 7. It is blue.
Do you see that these two graphs do not intersect?
Because they don't, there is no solution. Any marker will accept this explanation and the graph. You should be fine with just this much.
50/36 = 1.39 per litre (or 1.86 dollars for those in the United States)
6 squared units
Hope this helps!
oh and here is the formula and substatution..
A=(b*h)/2
A=(6*2)/2
30.55 * 13=2.35
The width would be 2.35
So how many decimal places do you see?
Unless if you have the solution for a you can find b
