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
First you have to do

.
Since the car is moving at a constant rate, the answer would be
8h.
Is there more to this? I don’t quite understand
Answer:
A 
Step-by-step explanation:
Perimeter = the sum of all side lengths
Perimeter = 
Perimeter = 15 (in this case)
so...

And we're trying to solve for x.
Step 1. Subtract 6 to both sides

Step 2. Add 3 to both sides

Step 3. Combine like terms

Step 4. Solve for x


Answer:
