Subtract the sine term and take the square root.

Answer:
l=15
Step-by-step explanation:
let length=l
width=w
l=3w-2
w=(l+2)/3
Perimeter P=2(l+w)=2[l+(l+2)/3]=2(4l+2)/3≤43
2(4l+2)≤129
8l+4≤129
8l≤125
l≤125/8
so l=15
________________
P=2(l+w)=2(3w-2+w)=8w-4≤43
8w≤47
w≤47/8
l≤141/8-2
l≤125/8
l=15
Answer:
On multiplying the equation by 100 we will get 
Step-by-step explanation:
Given data in the question:-

We have to multiply the equation by 100.
Solution:-
We can write 0.03 as 3/100

Hence the answer is 12-x.
X= 7
This is because of you plug in 7 for x into the equation it will give you 28-10 which is 18.
The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
This is basically just finding unit rate and multiplying.
