Answer: t= -0.799
This can also be written as t= -0.8
How to do it :
4.74t+ 5 = 13.5t + 12
first, subtract 4.74t from both sides
5= 8.76t + 12
next, subtract 12 from each side
-7 = 8.76t
next, divide 8.76 from each sides
-0.799 = t
The equation is "x=0", because the x intercepts at the x axis with no y-intercept.
The length should be 10 bc area = length x with . and 10 times 10 is 100
