N = 4 + x? i think, im not really sure but im pretty sure it is
Expand
simplify x - 5x + 35 to -4x + 35
subtract 35 from both sides
simplify -7 - 35 to -42
divide both sides by -4
two negatives make a positive
simplify 42/4 to 21/2
Answer: x = 21/2.

Answer:
Step-by-step explanation:
in tri ADC and tri BDC
∠ADC =∠BDC = 90
DC is common
AD = BD (given)
triangle ADC ≅ tri BDC by SAS congruency
hence AC = BC by CPCT ( congruent parts of congruent triangles)
hence, BC = 13
