Answer:

Step-by-step explanation:
Notice that A, B, and C constitute the vertices of a right angle triangle, with the right angle at the vertex A.
If we count the number of squares separating B and A (one of the legs of the right angle triangle) we find 8 units.
If we count the number of squares separating C from A (the other leg of the right angle triangle), we get: 3 units.
Then, we apply the Pythagorean theorem to find that length of the triangle's hypotenuse which is the segment BC:

Answer:
3n + 3
Step-by-step explanation:
Mia is correct
When n= 1 , 3n + 3 = 3*1 + 3 = 3 + 3 = 6
When n =2, 3n + 3 = 3*2 + 3 = 6 + 3 = 9
When n = 3 , 3n +3 = 3*3 + 3 = 9 + 3 = 12
When n = 4, 3n + 3 = 3*4 + 3 = 12 +3 = 15
No it's longer because 1.29 is bigger
Answer:
3 1/3
Step-by-step explanation:
Answer:
(7-4i)+(-2+5i) = 5 + i
Answer = 5 + i
Step-by-step explanation:
Group the real part and the imaginary part of the complex number
( 7 - 4i ) + (-2 + 5i )
= ( 7 - 2 ) + ( -4 + 5 ) i
Refine = 5 + i
