Answer:

c = 9/16

Step-by-step explanation:

<h3>step1</h3>

(a-b)²

a² - 2ab + b²

here a = x

        b = ?

   

so

x² - (2)(x)(?) + ?²

Now we can see that -(2x)? = -3x/2

                                    -2x? = -3x/2

cancel -x on both sides

2? = 3/2

? =  3/2 * (2)

? =  3/4

so b = 3/4

<h3>step2</h3>

(x² - 3x + 9/16) = (x-3/4)²

so from the expression we can see that C = 9/16

Remove the parentheses from the following expression and combine like terms. 3(ax + b2 - c) + 2
melisa1 [442]
To remove the parentheses, you just distribute. 
So, it will become 3ax + 3b^2 - 3c +2. I don't think there is any like term in this expression.

PLEASE HELP ME QUICKLY!!! Given that N:{1,2,3,5,8,13} and M:{−9,−8,−6,−4,−2,4}, which statements about N and M are true?
Lelechka [254]

Answer:

The intersection of N and M contains only those elements that are in both N and M.

The intersection of N and M is ϕ.

​N∩M=∅

Step-by-step explanation:

Given

M = { 1, 2, 3, 5, 8, 13}

N = {-9, -8, -6, -4, -2, 4}

Now let us see each statement one by one.

The intersection of N and M contains only those elements that are in both N and M.

The statement is true because by definition intersection of two sets consists of common elements of both sets.

The intersection of N and M is ϕ.

The statement is true. As there is no common element in both sets.

The intersection of N and M is {−9,−8,−6,−4,−2}.

The statement is false because there is not common element in M and N.

N∪M=∅

The statement is false as the union consists of elements of both sets so it can't be empty.

​N∩M=∅

True. Because no common element so intersection will be an empty set..
