Answer:
7
Step-by-step explanation:
= AC × CB
= ( x + 9 ) 9
144 = 9x + 81
9x = 144 - 81
9x = 63
x = 63 ÷ 9
x = 7
40! When you add all four angles of a quadrilateral together, you will always end up with 360. So, 360-75-120-125=40 :) have a great day!
The answer is f(x) = 3/2(3/2)^x. Hope this helps
10 kids total
picking Truman would be 1 out of 10 or 1/10
then there would be 9 kids left so picking Ryan would be 1 out of 9 or 1/9
the probability of picking both would be 1/10 * 1/9 = 1/90
