Answer: The common difference, d of the arithmetic progression is 2
Step-by-step explanation:
In the sequence 7, 9, 11, we can see that an additional term is gotten upon the addition of 2, so it is an arithmetic progression.
given that that first term a , =7
and the second term a + d = 9
The common difference , d =(a + d) − a
d = 9 − 7
d= 2
37.68m this is my best guess sorry if it's wrong :)
In general, 23 more than a number is written as
In our case, x is 'twice a number'; thus,
Finally, the whole expression is
Answer:
perpendicular
because of the opposite signs
y=10
(y-10)^2=0
Take the square root of each side
sqrt((y-10)^2)=sqrt(0)
y-10 =0
Add 10 to each side
y-10+10=0+10
y = 10
