Answer with Step-by-step explanation:

We are given a arithmetic sequence as:

A(n)=-6+(n-1)(\dfrac{1}{5})

We have to find the first, fourth and tenth term

First term:

n=1

A(1)=-6+(1-1)(\dfrac{1}{5})

A(1)= -6

Fourth term:

n=4

A(4)=-6+(4-1)(\dfrac{1}{5})

A(4)=-6+\dfrac{3}{5}

A(4)=-\dfrac{27}{5}

Tenth term:

n=10

A(10)=-6+(10-1)(\dfrac{1}{5})

A(10)=-6+\dfrac{9}{5}

A(10)=-\dfrac{21}{5}

Could someone show me how you would factorise : 9a(squared) - 6ab + 12ac - 8bc
wlad13 [49]
9a^2 -6ab+ 12ac -8bc

This expression cannot be factorized because its terms don't have at least a common factor~
