Answer:
The value of 
Step-by-step explanation:
We have given 
d=1.7
We have to find 
So,
from the formula

When n=14




Using the formula:

When n=26
![s_{26}=\frac{26}{2}[2(-18)+(26-1)(1.7)]](https://tex.z-dn.net/?f=s_%7B26%7D%3D%5Cfrac%7B26%7D%7B2%7D%5B2%28-18%29%2B%2826-1%29%281.7%29%5D)
On simplification we get:

Answer:
250
Step-by-step explanation:
120 is 120 spaces from zero
-130 is 130 spaces from zero
130+120=250
250 spaces from each other
Answer:
A. 
Step-by-step explanation:
I'm not sure if this is right
The formula of the Simple Interest is:
I=PRT
P for Principle Amount ($1200)
R for Rate (5%=

= 0.05)
T for Time in years (4 years)
I = 1200 × 0.05 × 4
= $240
Add the interest to the principle amount to check the balance
$1200 + $240 = $1440
Answer:
D)6 units
Step-by-step explanation:
the answer is D because since side AB have the same y coordinate then you would have to either subtract or add the x. if one point on x is negative and the other is positive then you would add. but if they were both positive or both negative then you would subtract the x.
