Answer:
the answer is
9b²-3b
Step-by-step explanation:
9b-3
Step-by-step explanation:

We start with Left hand side
We know that csc(x) = 1/ sin(x)
So csc(2x) is replaced by 1/sin(2x)

Also we use identity
sin(2x) = 2 sin(x) cos(x)

4 divide by 2 is 2
Now we multiply top and bottom by sin(x) because we need tan(x) in our answer



We know that sinx/ cosx = tan(x)
Also 1/ sin(x)= csc(x)
so it becomes 2csc^2(x) tan(x) , Right hand side
Hence verified
the opposite or addictive increase of 5x is -5x.
the opposite or addictive increase of 5x + 8 is -5x -8.
125 per month-$20 per month expences=105 savings each month
800/105= number of months needed to save
Answer 7.6 (rounded) roughly about 7 and a half months. If shes paid monthly, then 8 montjs needed
Step 1: 198 ×
= 66, the number of men who left the party
Step 2: 256×
= 64, the number of women who left the party
66+64=130
Since 130 is the number of people that left, you would subtract it from the total number of people at the party originally.
198+256=454
454-130=325
So, 325 people are left at the party
