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 simplify, the result is:
-10</span><span>±5</span>√2 (It is the last option).<span>

Answer:
ADC = 22°
Step-by-step explanation:
if it's the angle bisector that means it's in the middle of the angle to if the original angle there was 44° then 44 ÷ 2 = 22
Seven hundred twelve thousandths turns into 0.712.
Do u need to graph?
or just need the x and y intercepts
Answer:
1.58 cm
Step-by-step explanation:
Area of a square = length ²
Area of the square = 15/6 cm²
Area of a square = length ²
15/6 = length²
Find the square root of both sides
√15/6 = √length²
√2.5 = length
1.58 cm = length
Alternatively,
√15/6 = √length²
√15/√6 = length
3.87 / 2.45 = length
1.58 cm = length
Therefore, side length of the square = 1.58 cm
