Step-by-step explanation:
So, in order to rationalize the denominator, we need to get rid of all radicals that are in the denominator.
Step 1: Multiply numerator and denominator by a radical that will get rid of the radical in the denominator. ...
Step 2: Make sure all radicals are simplified. ...
Step 3: Simplify the fraction if needed.
Of the 20 sandwiches prepared by Ali, Ben and Carla, Ali made a total of A) two sandwiches
Information of the problem:
- Total of sandwiches: 20
- Ali = x
- Ben = 3x
- Carla = 2*(3x)
To solve this problem we have to state the equation using the information of the problem:
Total of sandwiches = Ali + Ben + Carla
20 = x + 3x + 2*(3x)
20 = x + 3x + 6x
20 = 10x
x = 20 / 10
x = 2
Substituting the (x) value into the information of the problem we get:
Ali = 2 sandwiches
Ben = 3*2 = 6 sandwiches
Carla = 2*(3*2) = 2*6 = 12 sandwiches

The answer is B because C and D are not true. Angle-Angle theorem does not prove congruency. Hypotenuse-Leg does because having a hypotenuse means that the triangle is a right angle triangle, which means that 2 sides and an angle are congruent in the triangles. By Side-Side-Angle Theorem, the triangles are congruent.
(4+x)+x=22
= 4+2x=22
= 2x = 18
= x = 9.
