Answer:
ft
Step-by-step explanation:
Let x be the length of each side
- Turn it into an algebraic expression:
- 14 × 14 = 196
- So, x = 196

Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = (x - h)² + k (h, k) are the coordinates of the vertex
Given y = x² + 7x - 5
To express in vertex form use the method of completing the square
add/subtract ( half the coefficient of the x- term )²
y = x² + 2( )x + - - 5
y = (x + )² - -
y = (x + )² -
Hence
a = and b = -
X=6 because 2*6=12 and 12+4=16
If the x is squared, the parabola is vertical (opens up or down). If the y is squared, it is horizontal (opens left or right). If a is positive, the parabola opens up or to the right. If it is negative, it opens down or to the left.
I am honestly not sure about this answer... try Khan Academy. Or, try breaking it down into steps.
I hope this helped... sorry about that. I will try this concept soon. :)
