110.979
Step-by-step explanation:
62.7% * 177 = 0.627 * 177 = 110.979
No they are not! If you multiply 3/4 times 4 to get the denominator as 12, you would get 9/12 which is not equivalent
Answer:

Step-by-step explanation:
For #2, remember that
, so
Also, (a+b)(a-b), where a and b are any numbers, (a+b)(a-b)=
. Now, to simplify, or radicalize, a number with surds in the denominator, you have to multiply the denominator by its conjugate. If there is a complex number
, where a and b are any numbers, the conjugate is always
. Lets apply these rules. The conjugate of 4+6i is 4-6i, so do this:

Our answer is (28-3i)/(26)!
Look at the coordinates and trace those points to a corresponding number on the x or y axis. Then write the first number in the coordinate in the x value and the second number for the y value, repeat the process for the rest of the points.
Answer:
17
Step-by-step explanation:
4(3) + 5 = ?
12 + 5 = 17
