Our goal is to get r all by itself on one side of the equals sign. To do this, we'll first add s to both sides
k=2r-s
+s +s
k+s=2r
Now, to get r alone, we need to get rid of the 2. Since 2 is multiplied by r, we need to divide it from both sides to get r alone.
k+s=2r
/2 /2
(k+s)/2=r
Since there are no numbers, that's the final answer.

Step-by-step explanation:
Answer:
t
Step-by-step explanation:
both t and s represent x axis value, t is greater as is on the right side from s
<span>Write the quadratic function in the form:
f(x) = a(x-h)</span>²<span> + k
Given Function:
f(x) = 3x</span>²<span> + 18x + 28
Using the completing square method:
</span> f(x) = 3(x² + 6x + 28/3)
f(x) = 3(x² + 6x + (3)² - (3)² + 28/3)
f(x) = 3[(x+3)² - (3)² + 28/3]
f(x) = 3[(x+3)² - 9 + 28/3]
f(x) = 3[(x+3)² - 27/3 + 28/3]
f(x) = 3[(x+3)² - 1/3]
f(x) = 3(x+3)² - 1
Therefore,
The vertex is (h,k) = (-3,-1)
