we have

Step 
Move the constants to the right side

Step 
Factor 3 out of the variable terms

Step 
Add
to both sides of the equation


Step 
Write the polynomial as a binomial squared

therefore
the answer is
Factor 3 out of the variable terms.
Answer:
a person travel 50 ft from the bottom to the top of the escalator
Step-by-step explanation:
An escalator lifts people to the second floor of a building, 25 ft above the first floor. The escalator rises at a 30 degree angle
The escalator forms a right angle triangle
opposite to 30 degree angle is 25 feet. to find the distance from the bottom to the top of the escalator we find the hypotenuse
let x be the hypotenuse


a person travel 50 ft from the bottom to the top of the escalator
Answer:
The third option
Step-by-step explanation:
In order to use SAS congruence, you need to prove that BC is congruent to itself. This is called the reflexive property
