Solution steps

\frac{π}{4} - π

Convert element to fraction:

π = \frac{π 4}{4}

= \frac{π}{4} - \frac{π 4}{4}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{π - π 4}{4}

Add similar elements:

π - 4 π = - 3 π

= \frac{- 3 π}{4}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{3 π}{4}

5 x - 1 \leq 3 + 3 x

(6 + 43)^{2}

- \frac{0.8 ( 19 )}{( 0.01 ( 19 ) ^{2} + 1 ) ^{2}}

3 5^{2} + a^{2} = 9 1^{2}

5 x - 29 > - 34 or 2 x + 31 < 29
