This is a simple equation:
x - 7 < 14
x < 14 + 7
x < 21
→ Many people think that because there is not "=" sign they don't flip the sign of what in this case is -7. But actually, the symbols "<" and ">" act as the equal sign. This rule doesn't apply to positive number, only negative.

Answer:
<u>-5 ± √5² - 4 · 1 · 4</u>
2 · 1
Step-by-step explanation:
ax²+bx+c=0 (quadratic equation)
x=<u> -b ± √b² - 4ac</u>
2a
a= 1
b= 5
c= 4

Answer:
Last choice. d.
Step-by-step explanation:
We are given the first term and the sixth term.
The first term is 
.
The sixth them is 
.
Let's solve for the common ratio, r.
Divide both sides by -9:
Take the fifth root of both sides:
So the common ratio is 4.
