Mathematics
1 answer:
KATRIN_1 [288]3 years ago
7 0

Answer:

x is equal to 0.94 and -1.94

Step-by-step explanation:

3x² + 3x + 7 = 0

9x² + 9x + 21 = 0

9x² + 9x + 2.25 = 18.75

(3x + 1.5)² = 18.75

3x + 1.5 = ±√18.75

3x = -1.5  ±√18.75

x = (-1.5  ±√18.75) / 3

x = 0.94, -1.94

Reduce the following fraction: -32abc/64a^2bc^2
mafiozo [28]

Answer:

-\dfrac{1}{2ac}

Step-by-step explanation:

Given:

\dfrac{-32abc}{64a^2bc^2}

Reduce this fraction.

Work with numbers and different letters separately:

1. Numbers:

\dfrac{-32}{64}=-\dfrac{32}{32\cdot 2}=-\dfrac{1}{2}

2. Letter a:

\dfrac{a}{a^2}=\dfrac{a}{a\cdot a}=\dfrac{1}{a}

3. Letter b:

\dfrac{b}b}=1

4. Letter c:

\dfrac{c}{c^2}=\dfrac{c}{c\cdot c}=\dfrac{1}{c}

Hence,

\dfrac{-32abc}{64a^2bc^2}=-\dfrac{1}{2}\cdot \dfrac{1}{a}\cdot \dfrac{1}{c}=-\dfrac{1}{2ac}
