Triangle Area = .5 * base * height

48 = .5 * (x +4) * x

48 = (.5x + 2) * x

48 = .5x^2 + 2x

.5x^2 + 2x -48 = 0

x = 8

base = 12

marta [7]
S= number of small boxes
l= number of large boxes

equation 1:  s+l=120
equation 2:  15s+45l=3300

solve by elimination, multiply equation 1 by -15.

-15(s+l=120) =  -15s-15l=-1800  add to equation 2.

-15s+15s-15l+45l=-1800+3300  = 30l=1500

30l=1500 , l=50

s+l=120, s+50=120 --> s=70
