You have the right one selected.
The answer is 2:1
To find this take each side of ABC and its corresponding side on DEF, then simplify. You can treat ratios just like fractions, so simplify them in the same way.
20:10 becomes 2:1
12:6 becomes 2:1
16:8 becomes 2:1
Answer:
D
Step-by-step explanation: its a coeficcient because itd a number that has a variable along with it
Whenever you add or subtract fractions you have to have the denominators the same so that the numerator is of the same value system.
For example you have 8/16 - 8/32
If you were you to subtract it without changing denominators to the same it would be equal to zero but when you change them to the same denominator
16/32 - 8/32 then the answer would be 8/32.
Answer:
10 + 2i
Step-by-step explanation:
√−4 + 10
Simplify each term.
Rewrite
√−1(4) + 10
√−1 ⋅ √4 + 10
Rewrite √−1 as i
i ⋅ √4 + 10
i ⋅ √2^2 + 10
Pull terms out from under the radical, assuming positive real numbers.
i ⋅ 2 + 10
2i + 10
or
10+2i
