Answer:
-0.56 or -10.67 (rounded to nearest hundredth)
Step-by-step explanation:
quadratic formula is (-b +/- √(b^2 - 4ac))/2a, so
![\frac{-45 +/- \sqrt{45^{2} - 4(4)(24)}}{2(4)}](https://tex.z-dn.net/?f=%5Cfrac%7B-45%20%2B%2F-%20%5Csqrt%7B45%5E%7B2%7D%20%20-%204%284%29%2824%29%7D%7D%7B2%284%29%7D)
which equals
![\frac{-45 +/- 40.51 (rounded)}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B-45%20%2B%2F-%2040.51%20%28rounded%29%7D%7B8%7D)
when you simplify this, you should get
-0.56 or -10.67
Let's go shape by shape!
The area of a rectangle can be calculated as follows:
![L * W = area](https://tex.z-dn.net/?f=L%20%2A%20W%20%3D%20area)
where L = length and W = width
The area of a trapezoid can be calculated as follows:
where b1 and b2 = lengths of the base and H = height of the shape
The area of a parallelogram can be calculated as follows:
![B * H = area](https://tex.z-dn.net/?f=B%20%2A%20H%20%3D%20area)
where B = length of the base and H = height of the shape
1 kilometer is 1000 (or 10^3) meters, so Eric walks .81*10^3=810 meters and YiTing walks .65*10^3=650 meters.
Hey there!!
Let's take the first number as ' x '
Then, the second number would be ' x + 1 '
Sum of these = 183
Hence,
![x + x + 1 = 183](https://tex.z-dn.net/?f=x%20%2B%20x%20%2B%201%20%3D%20183)
![2x + 1 = 183](https://tex.z-dn.net/?f=2x%20%2B%201%20%3D%20183)
![2x = 182](https://tex.z-dn.net/?f=2x%20%3D%20182)
![x = \frac{182}{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B182%7D%7B2%7D)
![x = 91](https://tex.z-dn.net/?f=x%20%3D%2091)
Hence, the small integer is 91
Hope my answer helps!

to solve for x you'll have to subtract 6 from both sides then divide both sides by 7
