Find the Value of X. If your answer is not an integer, express it in simplest radical form.
Gennadij [26K]
For each question we must apply the Pythagorean theorem and clear the value of x.
 question 5 
 x = root (14 ^ 2 + 16 ^ 2)
 x = root (452)
 x = 2raiz (113)
 question 6
 
x = root (8 ^ 2 + 15 ^ 2)
 x = 17
 question 7
 
x = root (12 ^ 2 + 12 ^ 2)
 x = root (2 * (12 ^ 2))
 x = 12raiz (2)
 question 8
 x = root (18 ^ 2 - 9 ^ 2)
 x = root (243)
 x = 9raiz (3)

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

24 is 16% of what number
Eva8 [605]
Is/of = %/100 plug the numbers in 24/x = 16/100 then cross multiply then you get 2400 = 16x so you get x by itself so you would have to divide by 16. 2400/16 = 16x/16 the 16 on the x side cancel out so you get x = 150 (I used proportions)
