Mathematics
1 answer:
Ivan3 years ago
7 0

Answer:

x=2

Step-by-step explanation:

3(5x+2)=8x+20

Distribute the 3

15x +6 = 8x+20

Subtract 8x from each side

15x-8x +6 = 8x-8x+20

7x+6 = 20

Subtract 6 from each side

7x+6-6=20-6

7x=14

Divide each side by 7

7x/7 = 14/7

x=2

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
