Answer:
Step-by-step explanation:
w + g = 52
w = 4g - 3
(4g - 3) + g = 52
5g - 3 = 52
5g = 52 + 3
5g = 55
g = 55/5
g = 11....there are 11 green marbles
w + g = 52
w + 11 = 52
w = 52 - 11
w = 41 <=== there are 41 white marbles
It's simple, just subtract 3 from 6 because the have the same terms and variables then keep your answer as it should be. you should get 4b³c²+3b²c³

➷ Let the width be 'x' and the length be 'x + 2'
Area = l x w
Substitute the values in:
48 = x(x + 2)
48 = x^2 + 2x
Use trial and error [it'll only take a few turns] to get the value for x
x = 6
x + 2 = 8
Thus, the length of the paddock is 8m and the width is 6m.
