Answer:
-18
Step-by-step explanation:
![-4(-2)+\frac{(-12)}{+3}-20+(+4)+(-6)=8-\frac{12}{3}-20+4-6=8-4-20+4-6=-18](https://tex.z-dn.net/?f=-4%28-2%29%2B%5Cfrac%7B%28-12%29%7D%7B%2B3%7D-20%2B%28%2B4%29%2B%28-6%29%3D8-%5Cfrac%7B12%7D%7B3%7D-20%2B4-6%3D8-4-20%2B4-6%3D-18)
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
x² + x + 1 ← to obtain vertex form use metod of completing the square
To complete the square
add/ subtract (half the coefficient of the x- term )² to x² + x
x² + 2(
)x +
-
+ 1
f(x) = (x +
)² +
← in vertex form
Answer:
The ratio simplifies fully to 2:1
=======================================================
Work Shown:
4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5
2 & 1/4 = 2 + 1/4 = 2 + 0.25 = 2.25
The original ratio is the same as 4.5 : 2.25
Divide both parts by 2.25 and you'll end up with 2:1
4.5/2.25 = 2
2.25/2.25 = 1
This means the length is twice as long compared to the width.
