Option B is correct
because in a triangle the sum of the 2 sides must be greater than third side but in option B
12cm = 7cm+5cm
12cm = 12cm
hence it cannot form a triangle.
Answer:
true....... but only because it can be Lee's than OR equal to...
Step-by-step explanation:
brainliest pls! :)
-6x + 8y = 6 . . . (1)
-12x + 16y = 8 . . .(2)
(1) x 2 => -12x + 16y = 12 . . . (3)
(2) - (3) => 0 = -4
Therefore, the system has no solution.
Solution:- Let f and g be the functions such that
can be used to form a function which maps x in X to
in Z.
If z is a function of y, and y is a function of x, then z is a function of x. (transitive property)
Hence the composite function is given by
, defined by
for x in X.
Now , for the function g(x) into the function for f(x), we have to work from the inside out by substituting the expression. So by this way composition of function related to order of operations.
Answer:
a) 3 x 20 = 60
b) -2x20 = -40
question c and d are unclear as we do not know how many questions were wrong and how many were not answered.
Sorry but I hope that helped
