Answer:Width = 15 units .
Step-by-step explanation:
Given : The width of a rectangle is 4 more than half the length. If the perimeter of the rectangle is 74,
To find : what is the width.
Solution : We have given perimeter of the rectangle is 74,
Let the Length = x .
According to question :
The width of a rectangle is 4 more than half the length.
Width = 4 + .
Perimeter = 2 length + 2 width .
Plugging the values,
74 = 2 ( x ) + 2 (4+).
74 = 2x + 8 + x .
Combine like terms
74 = 2x +x + 8.
74 = 3x +8.
On subtracting both sides by 8.
74 -8= 3x .
66 = 3x
On dividing both sides by 3
x = 22.
Width = Width = 4 + .
Width = 4 +11.
Width = 15 units .
Therefore, Width = 15 units .

Answer:
7
6
5 ○ Perpendicular
Step-by-step explanation:
7 Halfway in between −2 and −6 is −4, and halfway in between 0 and 10 is 5, so you will have this:
6 Parallel Lines have SIMILAR <em>RATE</em><em> </em><em>OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so <em>line </em><em>r</em><em> </em>also has a slope of −1.
5 Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so −8⁄9 indeed becomes 1⅛ [or 9⁄8], therefore lines <em>r</em> and <em>q</em> are perpendicular.
