All quadrilaterals have 360 degrees in all 4 angles added up. If all 4 angles are congruent, they must all be 90 degrees, making it a rectangle. So the answer is true.

84% 84, percent of astrid's books are fiction. What fraction of astrid's books are fiction?
yuradex [85]

Let number of  books by astrid's = x

Out of x , 84% are fiction.

So, Number of non fictional books = x - \frac{84x}{100}

                                       =  \frac{100x- 84 x}{100} =  \frac{16x}{100}

→Ratio of number of  books to  fictional books

                                     =\frac{x}{\frac{84x}{100}}\\ = \frac{100}{84}\\= \frac{25}{21}⇒[Dividing numerator and denominator by 4.]

→Out of 25 books by astrid 21 are fictional.

→ Number of fictional books by astrid = \frac{21}{25}

Consider the quadratic equation x? = 4x - 5. How many solutions does the equation have? A The equation has one real solution. Th
anzhelika [568]

Answer:

{-1, 5} (two real solutions).

Step-by-step explanation:

On the left side we want x^2, not x?

We need to rewrite x? = 4x - 5 in standard form, that is, as a quadratic with x terms in decreasing powers of x:

x^2 - 4x + 5 = 0

This factors easily to (x - 5)(x + 1) = 0.

We let each factor equal zero (0) separately and solve for x:  

{-1, 5} (two real solutions).
