Y (9 + 2y)
= y (9) + y (2y)
= 9y + 2y²
= 2y² + 9y
The probability of the arrow will land on a section labeled with the number greater than 3 is 
Step-by-step explanation:
Given,
The spinner is divided into 8 sections say named 1, 2, 3, 4, 5, 6, 7, 8
To find the P : probability of the arrow will land on a section labeled with the number greater than 3
Formula
<u>P = (the number of possible outcomes) ÷ ( the number of total result)</u>
We will count the probability when the arrow land on either 4 or 5 or 6 or 7 or 8 = 5 times
Total number of result = 8
Hence the probability = 
Answer:
30 inches
Step-by-step explanation:
The area of a rectangle or square is length×width; the length is 3 inches and the width is 10 inches. So 3×10= 30 inches.
Answer:
b
Step-by-step explanation:
using the law of logarithms
• log
= nlogx
given
= 29 ( take log of both sides, that is base 10 )
log
= log 29, hence
tlog 3 = log29 (divide both sides by log 3 )
t =
≈ 3.0650 → b
X-6 = 15 / (-5)
x-6 = -3
x = -3+6
x = 3
