1. You con solve the quadratic equation x^2+20x+100=50<span> by following the proccedure below:
2. Pass the number 50 from the right member to the left member. Then you obtain:
x^2+20x+100-50=0
</span><span> x^2+20x+50=0
</span><span>
3. Then, you must apply the quadratic equation, which is:
x=(-b±√(b^2-4ac))/2a
</span><span>x^2+20x+50=0
</span><span>
a=1
b=20
c=50
4. Therefore, when you substitute the values into the quadratic equation and simplify ir, you obtain that the result is:
-10</span>±5√2 (It is the last option).
area = length times width, so length = area / width
5 1/5 mi^2 5.2 mi^2
Here, length = ------------------- = --------------- = 2.66666... mi = 2 2/3 mi (answer)
1 19/20 mi 1.95 mi
1.6 i think
add all the goals and divide by the amount of games?
1 mile is 6.6 times 800 feet.
Answer: 9.72
To make it easier you first remove( imagine)there is no decimal point. Then u multiply the number which is 4 through all the digits to get 972.
But u are not done yet because u have forgotten the decimal point. To know where to put the decimal point u have to count the number of places it was in order to know where to place it.
So it was 2 decimal places,so we count it and place it there to get 9.72
