Answer: 7n - 13
Step-by-step explanation:
Apply the distributive property.
4n + 3n + 3 ⋅ -5 + 2
Multiply 3 by -5
4n + 3n - 15 + 2
Add 4n and 3n
7n - 15 + 2
Add - 15 and 2
7n - 13
hope this helps :)
Answer:
The shortest side has length 24 ft
Step-by-step explanation:
Try this: 3x + 4x + 5x =96 ft, or
12x = 96 ft
Then x = (96 ft) / 12, or x = 8
Multiplying this factor 8 by 3, we get 24. The shortest side has length 24 ft.
The middle-length side is 4(8), or 32.
The longest side is 5(8), or 40.
Check: Do 40 and 32 and 24 add up to 96 ft?
do 72 and 24 add up to 96 ft?
Yes.
It binomial experiment, random variable r represents the number of successes in n number of trials.
Answer:
y = 5x +2
Step-by-step explanation:
The point (0, 2) tells us the y-intercept is 2.
If we translate the table down 2 units by subtracting 2 from every y-value, it becomes ...
6, 30
-2, -10
0, 0
10, 50
We notice these values are all related by a factor of 5 (they are proportional). That means the equation will be a straight line with slope 5 and y-intercept 2.
y = 5x +2
