Answer:

12(x-1) (x-6)

Step-by-step explanation:

15(x - 4)(x -1)-3(x + 4)(x - 1)

We can factor out a 3 from both terms

3 ( 5(x - 4)(x -1)-(x + 4)(x - 1))

We can also factor out (x-1)

3(x-1) [5(x - 4)-(x + 4)]

Distribute inside the brackets

3(x-1) [5x-20 -x-4]

Combine like terms

3(x-1)[4x-24]

We can factor out a 4

3(x-1) 4[x-6]

12(x-1) (x-6)

Rule start at 5 and 1/2 add 1 1/5
Margaret [11]

Answer:

The solution is 6\frac{7}{10}.

Step-by-step explanation:

It is given that rule start at 5\frac{1}{2} add 1\frac{1}{5}.

From the given information, we get the expression

5\frac{1}{2}+1\frac{1}{5}

Simplify the complex fraction.

\frac{10+1}{2}+\frac{5+1}{5}

\frac{11}{2}+\frac{6}{5}

Taking LCM, we get

\frac{11\times 5+6\times 2}{2\times 5}

\frac{55+12}{10}

\frac{67}{10}

6\frac{7}{10}

Therefore the he solution is 6\frac{7}{10}.
