Mathematics
1 answer:
Anna35 [415]2 years ago

Answer:

\frac{b}{7a^2c} = \frac{5abc^2}{35a^3c^3}

\frac{a}{a - 4} = \frac{-a^2 - 4a}{16 -a^2}

Step-by-step explanation:

Given

\frac{b}{7a^2c}

Express the denominator as 35a^3c^3

To do this, we divide35a^3c^3 by the denominator

\frac{35a^3c^3}{7a^2c} = 5ac^2

So, the required fraction is:

\frac{b}{7a^2c} * \frac{5ac^2}{5ac^2}

\frac{5abc^2}{35a^3c^3}

Hence:

\frac{b}{7a^2c} = \frac{5abc^2}{35a^3c^3}

Given

\frac{a}{a - 4}

Express the denominator as 16 - a^2

Multiply the fraction a+4/a+4

So, we have:

\frac{a}{a - 4} * \frac{(a + 4)}{(a + 4)}

Apply difference of two squares to the denominator

\frac{a^2 + 4a}{a^2 - 16}

Take the additive inverse of the numerator and denominator

\frac{-(a^2 + 4a)}{-(a^2 - 16)}

\frac{-a^2 - 4a}{16 -a^2}

Hence:

\frac{a}{a - 4} = \frac{-a^2 - 4a}{16 -a^2}

5(k+5)+4&lt;21+6k what is the answer
Temka [501]
Solve whats in the parentheses first
5k+25+4<21+6k

5k+29<21+6k

plug in a number in k for both sides
5(1)+29<21+6(1)
5+29<21+6
34<27

5(2)+29<21+6(2)
10+29<21+12
39<33

so 5(k+5)+4 is greater than 21+6k
