Answer:
x = 11
Step-by-step explanation:
right triangle ABC
using Pythagoras' identity
BC² = 7² + 24² = 49 + 576 = 625 ( take square root of both sides )
BC = 
= 25
Since the triangles are congruent then corresponding sides are congruent.
ST = BC , that is
3x - 8 = 25 ( add 8 to both sides )
3x = 33 ( divide both sides by 3 )
x = 11
Answer:
-16x - 30
Step-by-step explanation:
4(-3x - 5) - (10 + 4x) = 4*(-3x) - 4*5 + (-1)*10 + (-1)*4x
= -12x - 20 - 10 - 4x {add like terms}
= -12x - 4x - 20 - 10
= -16x - 30
