Answer:
Step-by-step explanation:
arc ST is 122° , it's the same as that inner angle
arc RT ( not asked for, but needed ) is 180 °
then arc RS is 360 -180-122= RS
58= RS
Then SRT is a racing version of cars from Chrysler / Dodge :0 or also for this problem it's 180+58 =238°

Answer:
8x^2-x-8
Step-by-step explanation:
6x^2 + 3x – 9-(- 2x^2 + 4x – 1 )
6x^2 + 3x – 9+2x^2 - 4x + 1
6x^2+2x^2+ 3x- 4x -9+1
8x^2-x-8
Answer:
9.31
Step-by-step explanation:
Distance = 3 ⅘ x 2.45
3 ⅘ = 3.8
3.8 x 2.45 = 9.31
Answer: The first option.
Step-by-step explanation:
1. The formula for calculate the perimeter is:
P=2l+2w
Where l is the lenght and w is the width.
2. The first perimeter is:
![P_1=2(105m)+2(12.5m)=235m](https://tex.z-dn.net/?f=P_1%3D2%28105m%29%2B2%2812.5m%29%3D235m)
3. If you multiply the dimension by a scale of factor of 2, is the same as write the following expression:
![P_2=2(2l+2w)](https://tex.z-dn.net/?f=P_2%3D2%282l%2B2w%29)
Where
is the first perimeter.
4. Then:
![P_2=2(235m)=470m](https://tex.z-dn.net/?f=P_2%3D2%28235m%29%3D470m)
