Q # 6 please multiply help

Mkey [24]

This is a problem of Difference-of-squares. We know that for a difference of squares $a^2-b^2$ the factorization is given by:

$(a-b)(a+b)$

To learn this you need to remember that a difference means subtraction. So applying those concepts we can solve this problem step by step.

Applying distributive property:

$(2n)(2n-2)+2(2n-2)$

Applying distributive property again:

$4n^2-4n+4n+4$

Simplifying:

$4n^2-4$

The correct answer is C

Which decimal does not round to 10

daser333 [38]

Which decimal does not round to 10?
I am not sure but if the teacher allows you to pick more than one choice, circle all because I think none of them is rounded to 10.

How do you solve 1 - r = -5. Please Explain!!

Gemiola [76]

1-r=-5
add r to both sides so the one side cancels out, then it should be 1=r-5
then you add -5 on each sides (because what you do to one side you must do to the other) and it would then have r on its own side which would give you your answer of r=6. To check 1-6 does equal -5
