Answer:
58+4=62 Sienna’s height is 62 inches
Explanation:
Sienna’s height is 62 inches because Georgia’s height is 58 inches and she is shorter by 4 inches which means you have to add 58+4 which would equal 62.
Answer:
x = 14°
Step-by-step explanation:
here we can see ( 6x + 5 ) is parallel to 89°, has same angle.
6x + 5 = 89 .............. as they are similar
6x = 89° - 5°
6x = 84°
x = 84 / 6
x = 14°
Given a quadratic equation
![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
The solutions are given by
![\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=%5Cdfrac%7B-b%5Cpm%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
In your case,
![a=1,\quad b=3,\quad c=1](https://tex.z-dn.net/?f=a%3D1%2C%5Cquad%20b%3D3%2C%5Cquad%20c%3D1)
So, the solutions are
![\dfrac{-3\pm\sqrt{9-4}}{2}=\dfrac{-3\pm\sqrt{5}}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B-3%5Cpm%5Csqrt%7B9-4%7D%7D%7B2%7D%3D%5Cdfrac%7B-3%5Cpm%5Csqrt%7B5%7D%7D%7B2%7D)
So, the two solutions are
![x_1 = \dfrac{-3+\sqrt{5}}{2},\quad x_2=\dfrac{-3-\sqrt{5}}{2}](https://tex.z-dn.net/?f=x_1%20%3D%20%5Cdfrac%7B-3%2B%5Csqrt%7B5%7D%7D%7B2%7D%2C%5Cquad%20x_2%3D%5Cdfrac%7B-3-%5Csqrt%7B5%7D%7D%7B2%7D)
And they are approximated by
![x_1\approx -0.38,\quad x_2\approx -2.62](https://tex.z-dn.net/?f=x_1%5Capprox%20-0.38%2C%5Cquad%20x_2%5Capprox%20-2.62)
The answer would be 3
(Let me know if you want me to explain)
Hope this helps
