√(-80) = √(4²×5(-1)) = 4√5 √(-1) = 4√5i.
flipAnswer:
Multiplication
Step-by-step explanation:
The answer is multiplication because the multiplication by two will definetly flip the value of any sort of number that is non zero.
The group represents equivalent ratios.
Answer: Option B
<u>Step-by-step explanation:</u>
As we see carefully, the equation B represents the equivalent ratio. Because if you divide the 7 by 10 then you will get 0.7 and this 0.7 can also be written as 70% in percentage form. So, the correct answer is Option B.
Case A:
It can be written as that 0.75, 0.5, 0.8.this group does not represent equivalent ratios
Case B:
If you divide the 7 by 10 then you will get 0.7 and this 0.7 can also be written as 70% in percentage form. This group represents equivalent ratios
Case C:
It can writes as that 0.7,0.7.0.25 so this group does not represent equivalent ratios
Case D:
This gives 0.7, 0.14, 0.7 so this group does not represent equivalent ratios.
Here is the answer
4(2a+3b)(2a-3b)
