Answer: The difference is,
Step-by-step explanation:
Given expression is,
By distributive property,
Combine like terms( that have the same variables and powers ),
Which is the required result.
Hence, option third is correct.
First solve for parenthesis
73 + 27 = 100
x - 100 = 400
Isolate the x. Add 100 to both sides
x - 100 (+100) = 400 (+100)
x = 400 + 100
x = 500
500 is your answer for x

Answer: length = 7 feet's
Width = 6 feets
Step-by-step explanation:
Perimeter of a rectangle is the distance round the rectangle.
Perimeter of rectangle is expressed as
2(length + width)
The perimeter of the given rectangle is 26 feet. Therefore
2(L + W) = 26
Dividing by 2,
L+W = 13
The area of a rectangle is expressed as length × width
The given area is 42 square feet. Therefore,
L×W = 42
Substituting L = 13 - W into LW = 42, it becomes
W(13-W) = 42
13W - W^2 = 42
W^2 -13W + 42 = 0
W^2 -7W - 6W + 42 = 0
W(W - 7) - 6(W - 7) = 0
(W-6)(w-7)=0
W-6 = 0 or W-7=0
W=6 or W = 7
L= 13-6 or L= 13-7
L= 7 or L = 6
