If the scale factor is a number smaller than 1, then it is a contraction. If the factor is equal to 1, then it is congruent. If it is bigger than 1, then it is an expansion.
Answer:
Step-by-step explanation:
2(x+0.6) + 5(1.02-x) = 0
Opening the brackets
2x + 1.2 + 5.1 - 5x = 0
-3x + 6.3 = 0
-3x = -6.3
x = -6.3/-3
x = 2.1
B but technically its the square root of 34 which kinda equals 5 (exact: 5.83095...)
I do not know the answer to this i suck at math
