When you subtract and add what is in the parentheses you would get -15 so I’m guessing he didn’t go from left to right when working inside the parentheses but when you solve the whole problem out you would get the answer: -41.25 If I missed something or you need me to show the work just let me know but I hope this helps !
Notice that the box has a total os 4 + 5 + 3 = 12 balls, since there are 4 that are yellow, then, the probability to randomly obtaining a yellow ball in a single draw is:

therefore, the probability is 0.33 = 33%
Answer:
B
Step-by-step explanation:
The volume (V) of a rectangular prism is calculated as
V = length × width × height
Calculate the volume of each prism
Q → V = 8 × 4 × 5 = 60 ft³
R → V = 6 × 7 × 12 = 504 ft³
S → V = 4 × 10 × 12 = 480 ft³
T → V = 2 × 13 × 5 = 130 ft³
Prism R has the greatest volume → B
Answer:
-2
Step-by-step explanation:
3-2n=7
-3 -3
-2n=4
divide both sides by -2
n=-2
