The town is looking to expand a rectangular playing field that was 60 ft by 80 ft. They want to increase the total area of the field by 3200 sq ft by adding the same amount to both the length and width of the field. Which equation can be used to determine how much should be added to the length and width of the field? A (x)(x) = 3200 B (x)(x) = (60)(80) + 3200 C (60 + x)(80 + x) = 3200 D (60 + x)(80 + x) = (60)(80) + 3200

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?
