Plz help ill give u brainliest Use v = 3 and v = 6 to determine if the expressions 3v + 2(v + 1) – 4 and 16 + 3v – v are equivalent. Which statements are true? Check all that apply.
The value of both expressions when v = 3 is 13.
The value of both expressions when v = 3 is 22.
The value of both expressions when v = 6 is 28.
The value of both expressions when v = 6 is 46.
The expressions are equivalent.
The expressions are not equivalent.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
