Answer:
X=7 or x= 2
Step-by-step explanation:
![(4x - 8)(x - 7) = 0 \\ (4x - 8) = 0or(x - 7) = 0 \\ 4x = 8orx = 7 \\ x = 2orx = 7](https://tex.z-dn.net/?f=%284x%20-%208%29%28x%20-%207%29%20%3D%200%20%5C%5C%20%284x%20-%208%29%20%3D%200or%28x%20-%207%29%20%3D%200%20%5C%5C%204x%20%3D%208orx%20%3D%207%20%5C%5C%20x%20%3D%202orx%20%3D%207)

I think it is C
I just had a lesson ab this
The hare's final displacement is given by the Pythagorean theorem as
√((13 m)² + (4 m)²) ≈ 13.601 m
The time it took to get there was (31 min)*(60 s/min) = 1860 seconds.
The direction was arctan(4/13) ≈ 17.1° north of east.
The hare's average velocity was (13.601 m)/(1860 s) on a bearing of 72.9°.
0.00731 m/s ∠72.9°
_____
Velocity is a vector quantity having both speed and direction. Here, we choose to express the direction as a bearing measured clockwise from North.
Answer:
Since ΔABC ~ ΔQRS, we know that:
=> AB/QR = BC/RS
=> 2/n = 6/15
=> n = (2 × 15)/6 = 5
*You can also use AB/QR = AC/ QS to calculate n
