Answer:
AB = BC = AC = 15
Step-by-step explanation:
Since the triangle is equilateral then the 3 sides are congruent.
Equate any 2 sides and solve for x , that is
AC = AB , so
11x - 7 = 6x + 3 ( subtract 6x from both sides )
5x - 7 = 3 ( add 7 to both sides )
5x = 10 ( divide both sides by 5 )
x = 2
Then
AC = 11x - 7 = 11(2) - 7 = 22 - 7 = 15 , thus
AB = BC = AC = 15
 
        
             
        
        
        
Answer: D. 20
Elliot is taking an exam with 4 questions and each question has 4 possible answers. If he answer it correctly, he will get 5 points for each correct answer.
If we assume that he gets all of the 4 questions correct,
4 * 5
=20 points
        
             
        
        
        
When a cross section is cut from a triangular right prism which is perpendicular to the base, the shape would be a rectangle with the length equal to height of the prism and the width equal to x which is to be determined still since it would depend at what part the area was cut.
