- - 2*-9x
This is because you have "two times" which is 2*
The sum of a number = x
Opposite of 9 = -9
3*16^(1/3) =
3*(8*2)^(1/3)
3*8^(1/3)*2^(1/3)
3*2*2^(1/3)
6 times cube root of 2 choice B
It would be 24717 because you subtract 38773 from 14056
Answer:
Step-by-step explanation:
$18-$7.50= $10.50
Answer:
b
Step-by-step explanation:
use cos(r + s ) = cosrcoss - sinrsins to expand.
cos pi/3 cosx - <u>sin pi/3 sinx</u> + cos pi/3 cosx + <u>sin pi/3 sinx</u>
the two in bold cancel out.
cospi/3 cosx + cospi/3 cosx
pi = 180° in trigonometry.
cos 180/3 cosx + cos 180/3 cosx
1/2 cosx + 1/2 cosx
= cos x
