Answer:
3x + 15 = 9
3x = 9 - 15
3x = -6
x = -6/3
x = <u>-</u><u>2</u><u>.</u>
x = -2
Hope it helps
Thanks
It is equal to 0.
Step-by-step explanation:
I can simplify it as follows:
sinα sin(90 - α) - cos(90 - α)(cosα)
Now sin(90 -α) = cosα and cos(90 - α) = sinα) ( for α < 90)
So the expression becomes:
sinαcosα - sinαcosα
= 0 .
3(x+4) ≤ 36
3x + 12 ≤ 36
3x ≤ 24
x ≤ 8
hope it helps.
