Answer:
The concluding part
Step-by-step explanation:
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).
Step-by-step explanation:
100*77+72/4
100*77+18
7700+18
7718
Answer:
$36
Step-by-step explanation:
A percent is always out of 100, no matter what.
If you need to find the percent of something try cross multipling like this.
x/720 x 5/100
5 x 720 = 3600
100x = 3600
divide 3600 by 100
and you get 36
