Answer:
d= 2
Step-by-step explanation:
To find the common difference, take the second term and subtract the first
-2 - (-4)
-2+4 = 2
We add 2 each time
Lets check
Take the third term and subtract the second
0- -2
0+2 =2
The common difference is 2
Answer:
m∡P = 40°
Step-by-step explanation:
15m + 17 + 4m - 10 + 7m - 9 = 180
26m - 2 = 180
26m = 182
m = 7
∡P = 7(7) - 9 = 49 - 9 = 40
GCF=1
LCM=42.
hope this helps
Answer:
b = 5
Step-by-step explanation:
All quadratic equations are formed in the format of 
+ bx + c = 0
Using this formula, we can re-arrange the equation to fit the given format.
- 2 = -5x
+ 5x - 2 = 0
5 is plugged in for "b" in this equation, therefore b = 5.
