Step-by-step explanation:
?
5^2 - 6^2
is the difference of 2 squares
and = (5-6)(5+6) = -11
Answer:
-3x is the answer I'm pretty sure I think
The length will be 17.
Perimeter equation is L+L+W+W= Perimeter
9+9+W+W=Perimeter
I took 18 and subtracted it from 52 and got 34.
Since we are calculating one side length I divided by 2 which got me to 17.
Answer:
50
Step-by-step explanation:
rectangle area = 144 cm
Formula: A= L*H
The give the length which is 16
144 = 16*H
Since they gave u the area instead of the height, work backwards
144/16 = 16/16 *H
9 = H
Now you have the length and height
Length: 16
Height: 9
Perimeter is when you add up all the sides
The top and bottom of the rectangle is the length which is 16 so
16 + 16 = 32
The left and right side of the rectangle is the height which is 9 so
9 + 9 = 18
Now add then both
32 + 18 = 50
So the perimeter of the rectangle is 50
Hope this helped!
