Answer:
A
Step-by-step explanation:

A is the answer domain is the x
If you can't read it, I'll do my best to translate:
Z) 10^2 + 5^2 = 125
√125 = 11.18 = Z
Y) tan-1(5/10) = 26.57°
90 + 26.57 = 116.57
180 - 116.57 = 63.43°
5 ÷ sin(63.43) = 8.88 = Y
X) 11.18^2 + 8.88^2 = 203.8468
√203.8468 = 14.28
14.28 - 10 = 4.28 = x
All numbers are rounded to 2 decimal places, if you need any explanations for why I did something then just let me know :)
I hope this helps!
Answer:
Your answer should be C. 1/2(162 - 38)
Step-by-step explanation:
Answer:
A. 2 ( 10 x − 5 )
D. 10 ( 2 x − 1 )
Step-by-step explanation:
Given expression:
20x − 10
Find the equivalent expression
Check all that applies
A. 2 ( 10 x − 5 )
= 20x - 10
B. 2 ( 2 x − 1 )
= 4x - 2
C. 10 ( 20 x − 10 )
= 200x - 100
D. 10 ( 2 x − 1 )
20x - 10
The correct options are
A. 2 ( 10 x − 5 )
D. 10 ( 2 x − 1 )
