Answer:
3x + 2
Step-by-step explanation:
The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?
The shape of a poster = Rectangular shape
Hence:
The Perimeter of a Rectangle (Poster) = 2L + 2W
Where:
Length = Height = 7x + 10
Perimeter = 20x + 24
Therefore:
20x + 24 = 2(7x + 10) + 2W
20x + 24 = 14x + 20 + 2W
2W = 20x + 24 - (14x + 20)
2W = 20x + 24 -14x - 20
2W = 6x + 4
W = (6x + 4)/2
W = 3x + 2
Therefore, the width of the poster
= 3x + 2
Answer:x=1/4
Step-by-step explanation:
24x+3=9
-3 to both sides
24x=6
divide 24 both sides
x=6/24
simplify by 6
x=1/4
