B. Four less than three times a number
So we just need to round all the numbers to the nearest hundred and add.
391 --> 400
221 --> 200
16 --> 0
So 400+200+0=600
Hope this helps! If you have any questions just ask!

Answer:
x = 14 cm
Step-by-step explanation:
We can only solve for x if the triangles are similar. The arrows on the left and right legs say those are parallel. Since alternate interior angles at each of the transversals are congruent, the triangles are AA similar.
ΔABC ~ ΔDEC, so we have ...
EC/ED = BC/BA
x/(18 cm) = (35 cm)/(45 cm)
x = (18 cm)(7/9) = 14 cm
