5x2 would be 10 and 10-50x would be negative 40x and 40x + 125 would be 165x
Answer:
The equation that can be used to find the width is 2(13 + w) = 42
The width of the rectangle is 8 inches
Step-by-step explanation:
The formula of the perimeter of a rectangle is P = 2(l + w), where l is its length and w is its width
∵ One rectangle has a length of 13 inches
∴ l = 13 inches
∵ Its perimeter is 42 inches
∴ P = 42 inches
- Substitute the values of l and P in the formula of the perimeter
∵ 42 = 2(13 + w)
The equation that can be used to find the width is 2(13 + w) = 42
To find W divide both sides by 2
∴ 21 = 13 + w
- Subtract 13 from both sides
∴ 8 = w
The width of the rectangle is 8 inches
Answer:
3x5

Answer:
The coordinates of the other end is 
Step-by-step explanation:
Given
Required
Find the coordinates of the other end
Let Midpoint be represented by (x,y);
(x,y) = (5,2) is calculated as thus
So
and 
Where 
and 
So, we're solving for 
Solving for 
Substitute 5 for x and -6 for x₁
Multiply both sides by 2
Add 6 to both sides
Solving for 
Substitute 2 for y and 2 for y₁
Multiply both sides by 2
Subtract 2 from both sides
Hence, the coordinates of the other end is
