The length of a rectangle is 5 centimeters less than twice its width. The perimeter of the rectangle is 26 cm. What are the dimensions of the rectangle?A. length = 7 cm; width = 6 cm
B. length = 4 cm; width = 9 cm
C. length = 6 cm; width = 7 cm
D. length = 5 cm; width = 5 cm
Answers
this translates to
L = 2W - 5
Perimeter = 2L + 2W = 26
we plug in L = 2W - 5 into 2L + 2W = 26
and get
2(2W - 5) + 2W = 26
distribute the 2
4W - 10 + 2W = 26
add like terms
6W - 10 = 26
add 10 to both sides
6W = 36
divide both sides by 6
W = 36 / 6 = 6
so the width = 6 cm
The only option with width = 6 cm is A
Therefore your answer is A

The following points that are on the line given by the equation y=2x are Options (D). (3,6) and (F). (5,10).
What is a straight line ?
A straight line is a line passing through the x-y plane that has equal intercepts with respect to the x axis and the y-axis. The slope of a straight line is always equal. The straight line is also satisfied by the coordinates points in the x and y axis respectively.
How to identify the points on the given line y = 2x ?
To identify the points satisfied by any given equation, we have to replace the points given in the following equation.
Taking first point in option (A) , (16,8) , we have y = 8 and x = 16 which does not satisfy the equation y = 2x .
Taking second point in option (B) , (1,3) , we have y = 3 and x = 1 which does not satisfy the equation y = 2x .
Now from the following options, checking points in Option (D) where x = 3 and y = 6 which satisfies the equation y = 2x .
Also checking the points in Option (F) where x = 5 and y = 10 which satisfies the equation y = 2x .
The following points that are on the line given by the equation y=2x are Option(D). (3,6) and Option(F). (5,10) .
