Answer:
rational
Step-by-step explanation:
its decimal expansion terminates after 9 and it can also be represented as fraction.
Answer:
<u>The answer for this equation is x = 7</u>
Step-by-step explanation:
1. Solve for x given that CE=36
9 + 3x + 6 = 36
3x + 15 = 36
3x = 36 - 15 (Putting x on the left side and all the numeric values on the right)
3x = 21
<u>x = 7 (Dividing by 3 at both sides)</u>
2. Proof of replacing x by 7
9 + 3 (7) + 6 = 36
9 + 21 + 6 = 36
<u>36 = 36</u>
<u>It proves that x = 7 is correct</u>
To solve 4(x-2)^2 = 16
divide each side by 4 to have (x-2)^2 = 4
take the square root of both sides
x-2 = -2 or x-2 = 2
add 2 to each side
x = 0 or x = 4
4 ( 0-2)^2 = 16
4 (-2)^2 = 16
4 (4) = 16 true
4 ( 4-2)^2 = 16
4 (2)^2 = 16
4 (4) = 16 true.
the values for x are 0 and 4.
Yes obviously this is riggh
