Product of odd number of negative terms is negative.
Hence, I have given all the 8 possibilities.
Please refer to the table attached.
Answer:
|x|=6 we have x1=-6 x2=6
|x|=3.2 we have x1=-3.2 x2=3.2
|x|=0 x=0
Answer:
1. a) the square root of 20
2. d) the square root of 52
Explanation:
we can use the formula of pythagoras' theorem, which is a² + b² = c² (with c being the hypotenuse of a right-angled triangle while a and b are its other two sides), to solve these questions.
for the first question, we can place the given values into the equation to get 4² + b² = 6², with b being the unknown here. b is thus equivalent to 6² - 4², or <u>√20</u>.
for the second question, we can get 4² + 6² = c², which is the unknown value in this question. it would be <u>√52</u>.
i hope this helps! :D
