Answer:
13/10
Step-by-step explanation:
Its 13/10...
please give brainliest
Alright, lets get started.
Suppose the original deck size: width = x feet
the width is one-fourth the length given in question means length = 4 x feet
Means the originally area = 
Now the dimensions are changed.
New dimensions, width = (x + 6)
new length = (4x+10)
So, new area will be = 
the area of the new rectangular deck is 128 ft2 larger than the area of the original deck, means

Subtracting
from both sides

Subtracting 60 from both sides


Dividing 34 in both sides


Means width = 2 feet
Length would be = 4 time width = 4 * 2 = 8 feet
Means dimension of original deck would be = 2 feet and 8 feet :Answer
Hope it will help :)
Answer:
x = 0
Step-by-step explanation:
You know the answer to this because you know the identity element for addition is 0: 5 + 0 = 5.
__
Or, you can make use of the addition property of equality and add -5 to both sides of the equation:
5 - 5 + x = 5 - 5
x = 0 . . . . . . . . . . simplify
