Sauron [17]
The possible combinations are:
1,9
2,8
3,7
4,6
9,1
8,2
7,3
6,4

Total straws: 9
Probability of first being 1: 1/9
Probability of second being 9: 1/8
Probability of both: 1/9 x 1/8 = 1/72

This will be multiplied by 8 as there are 8 possible combinations:
8 x 1/72
= 8/72
= 1/9

The length of a rectangle is (x-6) cm and the width is (x-9) cm. Calculate the value of x if the perimeter is 6 cm.​
GaryK [48]

Answer:

X=9

Step-by-step explanation:

perimeter =2L+2B

6= 2(x-6)+2(x-9)

6= 2x- 12+2x- 18

6= 4x-30

4x=30 + 6

4x=36

divide both sides by 4

x= 9

The ones with a base < 1 will decrease rapidly, then slowly. The one with a base > 1 will increase slowly, then rapidly. The y-intercept is the multiplier in front of the base.
