1. A test was carried out on a electrical circuit and the following resaults obtained:
4t1+t2=6
-3t1+5t2=0
the 1s and 2s are lower case dont know how to do it sorry!
solve analytically the above simultaneous equatios and check your answer by plotting their graphs on the same set of axes
2. the area of a rectangle is 25.2m2 (squared) and the width is 3.2 metres shorter than the length. calculate the dimentions of the rectangle.
3. solve by factorising the following equations:
x(squared)-6x+9=0
6x(squared)+x-15=0
if anyone can work these out or help me i would be much app cheers!
no i dont this has just completly confused me ! i realy havent a clue for these ive looked at my notes and i couldnt find anything :S i need each question broken dwn induvadually so do these i cannot find any notes on these in my books from previous lessons these re only practice questions ready for my summer exam it jus the fact that im trying to get these into my head with out using notes as my exams are not open book (allowed to look at notes whilst in exam)
