<span>Let us use the variable x for length. So width will be 1/2x + 3.
Perimeter = x+x+ 1/2x + 3 +1/2x + 3 = 3x + 6 = 66
Therefore 3x = 66-6 = 60
So x = 60/3 = 20
The length is 20 cm.
Therefore the width = 1/2 of 20 + 3 = 10 + 3 = 13 cm
Check: 20+20+13+13 = 66</span>
Answer:
x=2
Step-by-step explanation:
2x=4
x=4/2
x=2
The probability is zero because there is only red green and blue
M = 9
7 times 9 equals 63 and then you add 8 it equals 71.
7x9=63+8=71
