-8x+4... hope it helped.;)
The answer is “A” as when the width is multiplied by the row foot, you get approximately 3 times the amount.
I hope that’s correct and I hope I could help :)
Answers:
where 'a' cannot be zero.
=========================================================
Explanation:
The vertex is (h,k)
The x coordinate of the vertex is h which is found through this formula
For example, if we had the quadratic , then we'll plug in a = 3 and b = -6 to get:
------------
To find the value of k, we plug that h value into the original standard form of the quadratic and simplify.
It's interesting how we end up with the numerator of which is similar to found under the square root in the quadratic formula. There are other ways to express that formula above. We need to avoid dividing by zero. The values of b and c are allowed to be zero.
Step-by-step explanation:
8²+x²=17²
74+ײ=289
x²=225
Sq root both sides
x=15
15×8=120 Sq ft
