The perimeter is 46cm
you find the width by dividing the area by the length and then add the length and width times 2 to get the perimeter
20:30 so it becomes 2:3 as a fraction it would be 2/3. a fraction is basically a ratio.
Only if it's an even number.
Answer:
xy^(2)z^(6)
Step-by-step explanation:
i hope that helps you :)
Solution: (2,8)
Using the elimination method set up the system of equations like:
y = x + 6
y = 3x + 2
Eliminate the x-variable by multiplying the top equation by -3
-3y = -3x -18
y = 3x + 2
Combine terms:
-2y = -16
-y = -8
y = 8
Plug in 8 to one of the first equations for y
8 = 3x + 2
6 = 3x
x = 2
Solution: (2,8)
