Answer:

the length of MN is 5(1), or 5

Step-by-step explanation:

Segments add up to 9x here:  4 + 5x = 9x, so 4 = 4x and x must therefore be 1.

Then the length of MN is 5(1), or 5, and the length of LN is 9(1) = 9.

Answer:

5

Step-by-step explanation:

LM + MN = LN

4+5x = 9x

Subtract 5x from each side

4+5x-5x = 9x-5x

4 = 4x

Divide by 4

4/4 = 4x/4

1 =x

We want MN

5x =5*1 = 5

MN =5

We want to factor the following expression: 25x^2−36y^8 We can factor the expression as (U+V)(U-V) where U and V are either cons
Aneli [31]

Answer:

U=5\,x

V=6\,y^4

Step-by-step explanation:

Recall that an expression that can be factored as (U+V)(U-V) using distributive property for multiplication of binomials, should render:  U^2-V^2 (the factorization given above is that of a difference of squares. Then, the idea is to write the original expression :

25\,x^2-36\,y^8

as a difference of perfect squares. Let's examine each term and its numerical and variable form to find if they can be written as perfect squares:

a) the term   25\,x^2=5^2\,x^2=(5x)^2 therefore, if we assign the letter U to 5\,x, the first term becomes:

25\,x^2=(5\,x)^2=U^2

b) the term   -36\,y^8=-6^2\,(y^4)^2=-(6\,y^4)^2  therefore, if we assign the letter V to  6\,y^4 , this second term becomes:

-36\,y^8=-(6\,y^4)^2=-V^2

With the above identification, our expression can now be factored as a difference of squares:

25\,x^2-36\,y^8=(5\,x)^2-(6\,y^4)^2=U^2-V^2=(U+V)(U-V)

Please help I really don't get this I will give you 131 points that are all of them HELP ME SOON
zlopas [31]
The answer is 120 seconds.

Why?
180 divided by 4.5 is 40 seconds
200 divided by 2.5 is 80 seconds
Then add the seconds.
But I don’t understand how you walk so many meters in 180 seconds
