Which statement is NOT true?
elena-s [515]
If x ^ 2 = 100, then x = 10.

 
For this case what you should know is the correct clearance of the following equation:
 x ^ 2 = 100

 We then have two possible solutions:
 x=+/- \sqrt{100}
 Rewriting we have:
 x=+/-10
 Therefore, the solutions are:
 x1=10

x2=-10
 Answer:
 
A statement that is NOT true is:
 
If x^2 = 100, then x = 10.

Answer:

x + y = 90 - - - (1)

y = 1/4x - - - - (2)

Step-by-step explanation:

x = larger acute angle

y = smaller acute angle

Recall:

A right angle measures 90°

Sum of angles in a triangle = 180°

y = 1/4x

Hence :

90 + x + y = 180

x + y = 180 - 90

x + y = 90 - - - (1)

y = 1/4x - - - - (2)

Put y = 1/4x in (1)

x + 1/4x = 90

1.25x = 90

x = 90 / 1.25

x = 72

x + y = 90

72 + y = 90

y = 90 - 72

y = 18
