Can someone please clearly and correctly work out Q19? Would appreciate it a lot! :)

x^{2} +10x+30
I always start by moving the last term to the other side
x^{2} +10x=-30
To complete the square you take term 'b' , divide it by 2 then square it
( \frac{10}{2} )^2 = 25
We have to add 25 to what we have and what you do to one side you have to do to the other
x^{2} +10x+25=-30+25
x^{2} +10x+25=-5
Now we factor what is on the left side of the equation
(x+5)^2=-5
The last step is to move our right side of the equation back over 
(x+5)^2+5 - which is your answer :)))

There are approximately 1.2×10 to the eighth household in the US if the average household uses 400 gallons of water each day wha
lana [24]

Answer:

Total = 4.8 * 10^{10}

Step-by-step explanation:

Given

h = 1.2 * 10^8 --- households

g = 400 --- gallons

Required

The number of households

To do this, we simply multiply the average households by the gallons.

Total = g* h

Total = 400 * 1.2 * 10^8

Total = 480 * 10^8

Rewrite as:

Total = 4.8 * 10^2 * 10^8

Total = 4.8 * 10^{10}
