Sorry i'm asking a lot of questions i just dont understand

answer:

x=1 or   x= 1/2

step-by-step explanation:

given equation is:

(2x-2)(8x-4)=0

we have to find the value of x.

the zero-product property states that

if x.y=0 then x=0 or y=0 or both.

apply the zero-product property to the given equation.

(2x-2)(8x-4)=0

2x-2=0 or 8x-4=0

first solve 2x-2=0

adding 2 to both sides of above equation,we get

2x-2+2=0+2

2x+0=2

2x=2

dividing by 2 to both sides of above equation,we get

2x/2=2/2

x=1

now, solve 8x-4=0

adding 4 to both sides of above equation,we get

8x-4+4=0+4

8x=4

dividing by   8 to both sides of above equation,we get

8x/8=4/8

x=1/2

hence,the solution is x=1 or x=1/2.

answer:

step-by-step explanation:

first, see if you can group the terms. i will first put this in latex to make it easier to understand. we have , and we can factor a out of the first group, and a out of the other group, to get let's multiply everything by -1 now to ge t multiplying all this does not change it, because -1^2=1.

because a^2-b^2=(a+b)(a-b), we get out final answer as .

answer:

1.) 46.66 (many sixes)   2.) 4180.5

step-by-step explanation:

well. its easy, you just need to divide the work.

1) 13.82 /0.3  

=46.066667

2.) 863.1/0.2

=4180.5

hope this ; )
