The equation that is equivalent to 15-7x=14 is x=7
9h^2+42h+49
no common factors
trial and error
try first term and last term
all sings are positive since last term and middle terms are possitive
factor leading term and coeficient and try those
9=3*3
49=7*7
(3h+7)(3h+7)
9h^2+21h+21h+49
9h^2+42h+49
true
(3h+7)(3h+7)=(3x+7)^2
answer is (3h+7)^2
answe ris ths second one
Answer:
B
Step-by-step explanation:
Answer:
It is commonly used as a method of measuring dissimilarity between quantitative observations
Step-by-step explanation:
Euclidean distance is an indicator of the true straight line distance in Euclidean space between two points. There is only 1 Dimensional space in an illustration where there is only 1 variable representing each cell (or case). The simple arithmetic difference will be the Euclidean length between two cells.
Hence the correct answer is
Euclidean distance is commonly used as a method of measuring dissimilarity between quantitative observation.
So Answer is (c).
