sorry I'm in 5 grade idc what that is tho
Answer:
A
Step-by-step explanation:
2x² + 5x = 12
2x² + 5x - 12 = 0
x² + 5x - 24 = 0
factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. the only pair that adds to 5 is 8 and 3
2x² - 3x + 8x - 12 = 0
split the equation and factor
2x² - 3x = 0 ||| 8x - 12 = 0
x(2x - 3) ||| 4(2x - 3)
therefore the pair is (2x - 3)(x + 4)
2x - 3 = 0
2x = 3
x = 3/2
or
x + 4 = 0
x = -4
Answer:
-35a
Step-by-step explanation:
Here, you just distribute: -7 * 5a
= -35a
Option B:
The 12th term is 354294.
Solution:
Given data:
and 
To find 
The given sequence is a geometric sequence.
The general term of the geometric sequence is
.
If we have 2 terms of a geometric sequence
and
(n > K),
then we can write the general term as
.
Here we have
and
.
So, n = 7 and k = 4 ( 7 > 4)


This can be written as



Taking cube root on both sides of the equation, we get
r = 3




Hence the 12th term of the geometric sequence is 354294.
