PL HEL ILL GIVE BRAINLEIEST Which sequence follows the rule y=2x+8?
A. 10,12,14,16,18
B .10,28,64,136
C. 1,11,21,31,41
D. 16,32,48,64,80
Pls explain or i will report you for just answering for points.

a

Step-by-step explanation:

as x would be numbers going up for example y=2(1)+8. 2 times 1 is 2 plus 8 is 10 then u do 2. 2(2)+8 is 2 times 2 which is 4 plus 8 that is 12 and no other sequence is 10,12 so it is A

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
