Hey There!
The answer to you're question is C, because squared means to the power of two. So, 39 * 39 is 1,521.

Answer:
34. E 2 1/2
36. C 6cm
Step-by-step explanation:
34. ABC's triangle has 4, as it is equivalent to ADE's triangle's 10. I added 4 and 6 because the whole triangle shown is ADE. Then I did 10/4.
36. The reasoning is that on the other side, there is 9cm and 6cm which is equivalent to AB and 4cm
It goes like: 9/6 = AB/4
9 times 4 equals 36, and 36 divided by 6 is 6. Therefore the answer is 6cm.
Answer:
Invertible functions
Step-by-step explanation:
An inverse of a function is one that reverses the operation of the function such that the result of the function on a variable, is reversed back to the initial variable
Therefore, when we have the the result of the function, f on x as y given as follows;
f(x) = y
The inverse of the function, g on the result, y gives the initial variable, x as follows;
g(y) = x
Example of invertible functions includes;
f(x) = x²
An example of a non-invertible function includes;
f(x) = 2·x².
Answer: The slope of the line is 2.
Step-by-step explanation:
Slope = change in y/change in x
Slope = (8-4)/(4-2)
Slope = (4)/(2)
Slope = 2
