Without knowing anything about the sequence, this is impossible to answer. But suppose the sequence is arithmetic, in which case each term differs by some constant 
:
Then we can write
and from the formula above, we see this means the 10th term in the sequence is 
. But that's all the specific info we can gather about such an arithmetic sequence. If we set the first term to be some unknown 
, then the sum of the first 19 terms in the sequence would be
If we knew one more term in the sequence, we could determine the value of and derive the value of 
(if the first term 
is not immediately given), and then go on to find an exact numeric value for the sum.
width = x
length = 2x+8
area = l x w
x<span>(2x+8)</span>=120
<span><span>2<span>x^2</span>+8x−120=0 </span>
</span>
<span><span><span>x^2</span>+4−60=0 </span></span>
<span><span><span>(x+10)</span><span>(x−6)</span>=0</span>
</span>
<span><span>x=−10 and x=6 </span></span>
<span><span> width has to be a positive number</span></span>

Answer:
139.888 $
Step-by-step explanation:
Data :
15 ft = 24.98$
So
1 yard = 3 ft
15ft / 3 ft = 5 yard
So
5 yard = 24.98$
28 yd / 5yd = 5.6
5.6 × 24.98 = 139.888
9514 1404 393
Answer:
- 4 3-point baskets
- 7 2-point baskets
Step-by-step explanation:
Let x represent the number of 2-point baskets Nicoli made. Then (x -3) is the number of 3-point baskets. The total number of points is ...
2x +3(x -3) = 5x -9 = 26
5x = 35 . . . . . . add 9
x = 7 . . . . . . . divide by 5
(x -3) = 4 . . . find the number of 3-point baskets
Jokic made 7 2-point baskets and 4 3-point baskets.
