What is the answer to -20+5p-7z
kobusy [5.1K]

" -20 + 5p - 7z " is not a question, and it doesn't beg for an answer.
It's an expression that stands for a number. 

In order to determine what the number is, you need to know the
values of 'p' and 'z'.  And if either of those changes, then the value
of " -20 + 5p - 7z " immediately changes too.  So the whole thing is
a 'moving target'.

Hi \\  \\ 3x\²-7x+4 ~~--\ \textgreater \  \boxed{\frac{-b\pm \sqrt{b\²-2ac} }{2a} } \\ a=3 \\ b=-7 \\ c=4 \\  \\ x= \frac{7\pm \sqrt{(-7)\²-2.3.4 } }{2.(3)}  \\  \\ x= \frac{7\pm5}{6} \begin{cases}x_1= \frac{7+5}{6}=2 \\  \\ x_2= \frac{7-5}{6}= \frac{1}{3}   \end{cases} \\  \\ \therefore~(2; \frac{1}{3}) \\  \\  \\
