<h2>Answer:</h2>

720 pounds

<h2>Step-by-step explanation:</h2>

Initially, we have that the amount of algae in the pond is 90pounds. Every four hours the amount of algae doubles. If we called t the time and W the amount of algae, we have that:

At \ t=0 \ hours, \ w=90 \ pounds \\ \\ At \ t=4 \ hours, \ w=2(90)=180 \ pounds \\ \\ At \ t=8 \ hours, \ w=2(180)=360\ pounds \\ \\ At \ t=12 \ hours, \ w=2(360)=720 \ pounds

Finally, <em>after 12 hours the amount of algae in the pond is 720 pounds</em>

Can a triangle be formed with the side lenghts of 8cm, 4cm, and 12cm
ioda
No, because the sum of the measures shorter legnths of the sides must be greater than the measure of the greatest angle

4+8=12
so therefor the side legnths if you tried to make into a triangle, it would make a line 12 units long

HELP PLEASE<br> A. 51.4<br> B. 50.0<br> C. 31.0<br> D. 39.5<br> E. None
Liono4ka [1.6K]
First, in order to find the length of side w, you must first find the angle W. 
A triangle must be 180 degrees in total. 93 + 37 makes the triangle only have 130 at the moment. 
180 - 130 = 50
So angle W is 50 degrees
Now using this, we can use law of sines.
\frac{w}{sin50} =  \frac{31}{sin37}
Now multiply sin 50 on both sides. It can be written like so:
\frac{31sin50}{sin37}
Now plug this in a calculator. 
Answer is 39.5

What is the solution set to the equation x^2+6x+3=0
marin [14]

Answer:

That is a quadratic equation in which

a = 1

b = 6

c = 3

The quadratic formula is:

x = [-b +- sqr root (b^2 -4*a*c)] / 2*a

x = [-6 +- sqr root (36 -4 * 1 * 3)] / 2

x1 = [-6 + sqr root (24)] / 2

x2 = [-6 - sqr root (24)] / 2
