化简 (21.33-9.16)/(3.5-1.5)

解答

化简

\frac{21.33 - 9.16}{3.5 - 1.5}

6.085

求解步骤

\frac{21.33 - 9.16}{3.5 - 1.5}

21.33 - 9.16 = 12.17

= \frac{12.17}{3.5 - 1.5}

3.5 - 1.5 = 2

= \frac{12.17}{2}

数字相除:

\frac{12.17}{2} = 6.085

= 6.085

6 x + 4 < 2 + 5 x

(x + 4)^{2} = 25

f a c t or 2 x^{3} - 8 x^{2} + 2 x + 12

- 3 a \leq - 24 or a + 8 \leq 11

\frac{x ^{2} - 7 x + 6}{x + 3} \leq 0
