Answer:
x = 10.39 to the nearest hundredth.
Step-by-step explanation:
this is a right angled triangle so we use the Pythagoras theorem:
12^2 = x^2 + 6^2
x^2 = 12^2 - 6^2
x^2 = 144 - 36 = 108
x = √108
x = 10.39 (answer).

Answer:</h3>
A. (0,0) is a solution to n=m and to n=4m.
<h3>
Step-by-step explanation:</h3>
The equations can be solved by any of the usual means. Using substitution, we have ...
... m = n = 4m
... m(4 -1) = 0 . . . . subtract the left side
... m = 0 . . . . . . . . divide by 3
... n = m = 0
The solution is (m, n) = (0, 0).
<span>17<=3-2x<=21
subtract 3
14<=-2x<=18
divide by 2
7<=-x<=9
now mutiply whole inequality by -1, this will reveres the inequality
-7>=x>=-9
or -9<=x<=-7
so there are mistakes in the line
the corrected lines are
17 less than or equal to 3 - 2x and 3 - 2x less than or equal to 21 (line one)
14 less than or equal to -2x and -2x less than or equal to 18 (line two)
-7 greater than or equal to x and x greater than or equal to -9 (line three)</span>
