Answer:
(3x + 11) units
Step-by-step explanation:
The length of a rectangle is 5(x+2) units.
The width of the rectangle measures (2x-1) units.
The difference between the rectangles length and width is given as:
Length - Width
(5(x + 2) - (2x - 1) units
(5x + 10 - 2x + 1) units
(5x - 2x + 10 + 1) units
(3x + 11) units
Therefore, the algebraic expression for the difference between the rectangles length and width is given as:
(3x + 9) units
Answer:
The 2 digit number is 36.
Step-by-step explanation:
Let the 2 digits be x and y . The 2 digit number is xy.
x + y = 9........(1)
The old number can be written as 10x + y and the new number as 10y + x.
10y + x = 10x + y + 27
9x - 9y = - 27
x - y = -3 ......(2)
Adding (1) and (2) we get:
2x = 6
x = 3
and therefore y = 9-3 = 6.

Answer:
<h2>Add -60 and 36.</h2>
Step-by-step explanation:
6(9x − 10) + 2(18 − 3x) = −8
<em>use the distributive property a(b + c) = ab + ac</em>
6(9x) + 6(-10) + 2(18) + 2(-3x) = -8
54x - 60 + 36 - 6x = -8 <em>combine like terms</em>
(54x - 6x) + (-60 + 36) = -8 <em>Answer: Add -60 and 36</em>
48x - 24 = -8 <em>add 24 to both sides</em>
48x = 16 <em>divide both sides by 48</em>
x = 16/48
x = 1/3
