Masteriza [31]

Answer:

Step-by-step explanation:

Distance between earth and moon in meters = 386400 x 10³ m

Speed of ship = 11184.7258 m / s

Time taken = distance of moon from earth / speed of ship

= 386400 x 10³ / 11184.7258

= 34.5471 x 10³ s

= 34.5471 x 10³ / 60 x 60 hour

x+(x+3)+x^2=75 Please help........ Everyone is giving me answers i know arent true...
son4ous [18]

x + (x + 3) + x^{2} = 75

so you will add up all of the x 's but NOT the x^2

2x + 3 + x^{2} = 75

Rearrange to put the x^2 in front of 2x

x^{2} + 2x + 3 = 75

subtract the 75 from both sides

x^{2} + 2x - 72 = 0
