Answer:
50 and 160
Step-by-step explanation:
good
A + 5x + 2 means . . .
a can be any number
5 is multipled by x
x can be any number
2 stays the same
So it would be . . .
a + 5x + 2
An example of this is a would be 6 and x would be 2 so it would be written as . . .
6 + 5(2) + 2 = 18.
Hope this helps
And have a NICE DAY .... :) :D
Also pick me as the brainiest answer/crown :)

Step-by-step explanation:
Aops Question
Answer:
See proof below
Step-by-step explanation
cot^2(x) - csc^2(x) = -1
In trigonometry identity
cot^2x = cos²x/sin²x
Csc²x = 1/sin²x
Substitute into the original expression
cos²x/sin²x - 1/sin²x
Find the LCM
(Cos²x-1)/sin²x .... *
Recall that sin²x+cos²x = 1
Sin²x = 1-cos²x
-sin²x = -1+cos²x
-sin²x = cos²x-1 .... **
Substitute ** into *
(Cos²x-1)/sin²x
-sin²x/sin²x
= -1 (RHS)
Therefore cot^2(x) - csc^2(x) = -1 (Proved!)
Answer:
0
Step-by-step explanation:
In the given expression, substitute -5 for x and 25 for y:
5|x|-y to the third power over x becomes
5|-5| - 25 25 - 25
------------------ = -------------- = 0
-5 -5
