Blue: P=4x +2+7x +7+5x-4 --> 16x +9-4=16x +5

Red: P=x+3+2x - 5 + x + 7 --> 4x + 10 - 5 = 4x + 5

Difference between the perimeter:

(16x + 5) - (4x + 5) = 16x + 5 - 4x - 5 = 12x

Perimeter when x = 3

Blue : 16x + 5 ⇒ 16(3) + 5 = 48 + 5 = 53

Red: 4x + 5 ⇒ 4(3) + 5 = 12 + 5 = 17

Answer:

The probability is 0.89 or 89%

Step-by-step explanation:

Probability

There are n=27 students in a certain Algebra 2 class. 18 out of them play basketball and 16 of them play baseball.

We also know 3 students play neither sport. This leaves 27-3=24 students playing sports.

The probability that a randomly chosen student plays basketball or baseball is:

$\displastyle p=\frac{24}{27}$

Simplifying:

$\displastyle p=\frac{8}{9}=0.89$

The probability is 0.89 or 89%
