Triangle A is dilated by a scale factor of 2. What is the ratio of the perimeter of Triangle A to the perimeter of Triangle B?
2 answers:
Answer:
the ratio is 1:2
Step-by-step explanation:
Triangle A is dilated by a scale factor of 2
Suppose we take triangle A with sides a,b,c
To find the perimeter we add all the side. So the perimeter of triangle A is
Triangle A is dilated by a scale factor of 2. So we multiply the sides of the triangle by 2. when we multiply the sides by 2 then sides becomes 2a,2b, 2c
Now the perimeter of triangle B is
So the perimeter of triangle B is 2 times the perimeter of triangle A
the ratio is 1:2

To make a square for x²+bx=c, add( 
)²on both side
in this case, b is-3/4, half of b is -3/8, and (-3/8)² is 9/64, so you add 9/64 to both side.
in this case, b is-3/4, half of b is -3/8, and (-3/8)² is 9/64, so you add 9/64 to both side.
