<span> (x + 3) • (x - 12)
</span>
The first term is, <span> <span>x2</span> </span> its coefficient is <span> 1 </span>.
The middle term is, <span> -9x </span> its coefficient is <span> -9 </span>.
The last term, "the constant", is <span> -36 </span>
Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 1</span> • -36 = -36</span>
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is <span> -9 </span>.
<span><span> -36 + 1 = -35</span><span> -18 + 2 = -16</span><span> -12 + 3 = -9 That's it</span></span>
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -12 and 3
<span>x2 - 12x</span> + 3x - 36
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-12)
Add up the last 2 terms, pulling out common factors :
3 • (x-12)
Step-5 : Add up the four terms of step 4 :
(x+3) • (x-12)
Which is the desired factorization
Final result :<span> (x + 3) • (x - 12)</span>

Answer:
25.2 weeks until everyone on the planet is infected
Step-by-step explanation:
The number of infected people after t weeks has the following format:
In which P(0) is the initial number of infected people and r is the growth rate, as a decimal.
The number of infected people doubles every week
This means that 
So
So
200-person town
This means that 
So
How long will it be until everyone on the planet is infected?
This is t for which P(t) = 7700000000[/tex]
So
25.2 weeks until everyone on the planet is infected
Good evening ,
Answer:
B. g(x)= -x² - 4
___________________
Step-by-step explanation:
The graph of g is downward facing then we must have (-) before the x²
Since, The vertex of parabola g is on point (0 ,-4) then we have to subtract 4.

Keep 6/15 the same and change Division sign into a multiplication sign and flip 4/21 and that will become 21/4.
126/60=21/10 and 21/10 as a mixed number is 2 1/10 so your answer is 2 1/10. Hoped I helped. :)
