2i or -2i
Step-by-step explanation:
2x² = -8 First, clear x.
x² = -8/2 Solve
x² = -4 Now, eliminate the square of x by solving the square root of -4.
x = √-4
x = 2i or -2i Is an imaginary number.
Answer:
7 and 14
Step-by-step explanation:
Given the LCM of two numbers to be 126
If one of the numbers is 18
The other number will be 126/18 = 7
The other possible value can be gotten by multiplying the lowest prime number by 7 i.e 2×7= 14
The two possible numbers are 7 and 14
If they have the same measure two circles are congruent if they have the same diameter
