Answer:
|5|, |-6|, |4|, |-3.5|...
Step-by-step explanation:
The absolute value is related with the distance between the number and the zero of the number line, then each number greater than 3 will have an absolute value greater than 3, as we can see in the picture, the numbers positive or negative will have a positive distance to the origin of the number line.
It would be 11.21 percent, hope it helps.
For the second one it should be 12 or -12
Answer:
The answer is 1 and 3/4
Step-by-step explanation:
Answer:
Step-by-step explanation:
a) 4x² + 20 = 0
4x² = -20
x² = -20/4
x² = -5 = i² *5
x = √i²5
x = i√5
b) 4x² + 5 = -7
4x² = -7 - 5
4x² = - 12
x² = -12/4
x² = -3 = 3i²
x = i√3
c) x² + 4x + 20 = 0
a = 1 ; b =4 ; c =20
= (-2 +4i) & -12/2
= (-2 + 4i) and (-6)
