Answer:
4
Step-by-step explanation:
diameter is 2 radius
Your answer would be 60 cm
Perimeter is when you add all sides together.
Length = 10 cm
Width = 20 cm
There are 4 sides and 2 of each has the same measurements.
So:
L = 10 x 2 = 20
W = 20 x 2 = 40
Add them.
40 + 20 = 60
Y= -x-1 the y-intercept =-1 and the slope=-1x
Answer:
6+4=10
8+2=10
5x2=10
