Remember: √-1=i
√-16=(√16)(√-1)=(i)(√16)=i(4)=4i
1-4i
Answer:
x = 6
Step-by-step explanation:
it states 6 times the quantity x - 2, so the expression would be 6 ( x - 2 ) = 24. first multiply because you cannot add or subtract unlike terms. so 6 multiplied by x and -2, the expression would be (6x - 12) = 24. add 12 to 12 so you cancel the coefficient. but when adding to the constant add to the sum. now it is 6x = 36. since 6x is multiplication, divide 6x by 6 to isolate the variable, but divide the answer, 36 divided by 6 is 6. therefore x = 6. hope this helps
3(2x+5)=3
3 • 2x] + [3 • 5] = 3
6x + 15 = 3
6x = –12
x = –2
2x – 2(3x – 2) = 2(x –2) + 20
2x – 2(3x – 2) = 2(x –2) + 20
2x – 6x + 4 = 2x – 4 + 20
– 4x + 4 = 2x + 16
–4x + 4 – 4 –2x = 2x + 16 – 4 -2x
–6x = 12
x = –2
