Answer:

32

Step-by-step explanation:

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

39 = 4x + 20 + 2x + 1

39 = 6x + 21

18 = 6x

x = 3

MN = 4(x + 5)

MN = 4(3 + 5)

MN = 4(8)

MN = 32

hope this helped!

Step-by-step explanation:

MP = MN + NP

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

39 = 4x + 20 + 2x + 1

39 = 6x + 21

6x = 39-21

6x = 18

x = 3

Then,

MN = 4(3+5)

= 4×8

= 32

The length of a photograph is 3cm less than twice the width. The area is 54cm². Find the dimentions of the photograph.
AnnyKZ [126]
L=2w-3 

w(2w-3)=54

2w²- 3w-54=0

A= 2 , B= -3, C= -54

sub values into quadratic formula
 i attached picture of formula

Final answer:  you will be given 2 answers 6 and -4.5. -4.5 is rejected since a negative value cannot represent length because that just doesn't make sense.

w=6

Check:
L=2w-3
=2(6)-3
=12-3
=9
  9*6=54

Therefore the dimensions of the photograph are 6 cm by 9 cm
