The expression which is equivalent to the provided expression of variable x is,
<h3>What is the equivalent expression?</h3>
Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.
The given expression in the problem is,
Let the equivalent expression of this expression is f(<em>x)</em>. Thus,
The number, with negative power, can be written in the fraction of 1 with the same but positive power or exponent. Therefore,
Solve it further as,
Hence, the expression which is equivalent to the provided expression of variable x is,

Answer:
10m is my answer
Step-by-step explanation:
Answer:
length = 8m and width = 5.5m
Step-by-step explanation:
Let the width be w
Length = 2w - 3
Given, Area = 44m2
Remember, area = length x width
Area = (2w - 3) X w. (expand the bracket)
Area = 2w² - 3w
2w² - 3w = 44
2w² - 3w - 44 = 0
Solve the quadratic equation
2 Factors of -44 that the sum would give -3 = +8 & -11
Rewrite the equation
2w² +8w - 11w -44 = 0 (factorise)
2w(w +4) - 11 ( w + 4) = 0
(2w - 11) ( w + 4) = 0
2w - 11 =0 or w + 4 = 0
2w = 11 or w = -4
W = 11/2 or -4
Width = 5.5m because we can't have a width that is negative.
Therefore length = 2w - 3
Length = 2(5.5) - 3
Length = 11 -3
Length = 8m
Dimension of rectangle is length = 8m and width = 5.5m
That is 8m by 5.5m
