Answer:  The equation is 5.25x = 21  and it will take Gary 4 weeks to exercise 21 hours.

Step-by-step explanation:

So we know a week is  7 days and Gary exercise 3 days out of the 7 days.

so we will have to multiply 3 * 1.75 to find the number of hours that  she exercise in 1 week.

3 * 1.75 = 5.25  so Gary exercises  5.25 for every week  so now we could use x to represent the number of weeks Gary will take to exercise 21 hours.

5.25x = 21  where x is the number of weeks.

x= 4

How do you complete the square to rewrite y= x^ -6x + 15 in vertex form
Vaselesa [24]
Vertex form of a quadratic equation is y=a(x-h)^{2}+k
where (h, k) is the vertex. 

Our aim is to write the expression y=x^{2} -6x+15 in the form 
y=a(x-h)^{2}+k



y=x^{2} -6x+15

y=x^{2} -2*3*x+15

y=(x^{2} -2*3*x+ 3^{2})-3^{2}+ 15

y=(x-3)^{2}-9+15

y=(x-3)^{2}+6

Find the length of side x in simplest radical form with a rational denominator.
Sauron [17]

Answer:

\frac{11\sqrt{2}}{2}} or 5.5√2

Step-by-step explanation:

We can see that this is a 45-45-90 triangle

refer to the image below to see what that means

we can see that (in the image) 11=x√2

which means that x= 11/√2

to rationalize this fraction we mulitply both sides by √2 to get

\frac{11\sqrt{2}}{2}} or 5.5√2
