Answer:
19404
Step-by-step explanation:
sum of arithmetic series is
Sn = n/2 (2a + (n-1)d)
or
Sn = n/2 (a + an)
a = 1st unit
an = last unit
d = difference
8-3 or 13-8 so d = 5
then first step is to find the value of n
an = a + (n-1)d
438 = 3 + (n-1)5
438 - 3 = 5n - 5
435 = 5n - 5
435 + 5 = 5n
440 = 5n
n = 440/5
n = 88
then we can find the sum
Sn = 88/2 (3 + 438)
S88 = 19404
We are asked to determine if the number sets 1857300 and 1857800 are the same number sets. To answer this, we need to recall and define that number sets are a collection of distinct objects such as elements and numbers. The answer to this question is that these two sets are NOT the same, the first one contains "3" while the second one contains "8".
Solve for x. The multiplicity of a root is the number of times the root appears.
x= -6.847415 (multiplicity of 1)
x= 0.793705 (multiplicity of 1)

Answer:
∠E = 48°
Step-by-step explanation:
The sum of angles in a quadrilateral is 360°.
(5x +3)° +88° +(10x +7)° +127° = 360°
15x = 135 . . . . divide by °; subtract 225
x = 9 . . . . . . . . divide by 15
Then angle E is ...
∠E = (5·9 +3)°
∠E = 48°
