Find the length of MN.<br> A) 7 <br> B) 25 <br> C) 32 <br> D) 39
MrRissso [65]

Step-by-step explanation:

Answer C)

Explanation:

MN + NP = MP

MP = 39

Therefore, 4(x + 5) + 2x + 1= MP

So, 4(x + 5) + 2x + 1= 39

(4x + 20) + 2x +1 = 39

So, (4x + 2x) + (20 + 1) = 39

6x + 21 = 39

Addition changes to Subtraction

So, 6x = 39 - 21

6x = 18

Multiplication changes to Division

x= 18/6

x=3

Therefore MN = 4(x + 5)

So, 4(3 + 5) = 4(8)

4(8) = 32

Therefore, MN = 32

Hope this helps!

Step-by-step explanation:

What steps should be followed to solve the inequality

-4x < 8

-4x < 8

Divide by -4 on each side and flip the sign.

So the equation becomes

\dfrac{-4x}{-4}> \dfrac{8}{-4}\\ \\

Now minus 4 will get cancel from left and side and in right inside -2 will be there such that (flip the sign)

\dfrac{x}{1}> \dfrac{-2}{1}\\\\\therefore x>-2
