Square Root
Oxana [17]

Answer:

1).(x+\frac{1}{4})^{2}=\frac{4}{9}

2).x+\frac{1}{4}=\pm \frac{2}{3}

Step-by-step explanation:

Here the given equation is x^{2}+\frac{1}{2}x+\frac{1}{16}=\frac{4}{9}

We have to factor the perfect square trinomial on the left side of the equation

So left side of the equation is x^{2}+\frac{1}{2}x+\frac{1}{16}

= x^{2}+2\times \frac{1}{4}x+(\frac{1}{4})^{2}

=(x+\frac{1}{4})^{2}    since [(a+b)²= a²+b²+2ab]

Therefore the factorial form of the equation will be

(x+\frac{1}{4})^{2}=\frac{4}{9}

Now we have to solve the equation by applying square root property

\sqrt{(x+\frac{1}{4})^{2}}=\sqrt{\frac{4}{9}}

x+\frac{1}{4}=\pm \frac{2}{3}

A person rides there bike at a rate of 1/4 mile every 3 minutes. What is there biking rate in miles per hour?
mario62 [17]
The answer is: 5 miles per hour

First we need to find out how many 3 minutes is in an hour. To do this, we need to divide 60 by 3= 20. Since we now that there are 20 (three minutes) in an hour (60 minuets), me can now multiply 20 by 1/4 of a mile= 5. That makes the answer 5 mph

Hope this helps and hope you have a great day
