Answer:
13 per minute
Step-by-step explanation:
15=3b
15/3 = 3b/b
5= b
Isolate the variable by diving 3 on both sides
First subtract the 7 from both sides and that would equal 2x+9=2x then subtract 2x and the answer is 9
Answer:
4,1
Step-by-step explanation:
The trigonometric equation <span> (sin Θ − cos Θ)^2 − (sin Θ + cos Θ)^3 can be simplified by:
</span>Using x for Θ:
<span>(sinx - cosx)^2 - (sinx + cosx)^2 </span>
<span>= (sin^2 x - 2sinxcosx + cos^2 x) - (sin^2 x + 2sinxcosx + cos^2 x) </span>
<span>= - 2 sinx cosx - 2 sinx cosx </span>
<span>= - 4 sinx cosx </span>
<span>= - 2sin(2x)
</span>
I hope it has come to your help.
