Answer:
The width is 2x+1
Step-by-step explanation:
10x^2 +5x
Divide this by 5x
10x^2 /5x = 2x
+
5x/5x =1
Add this together
2x+1
The width is 2x+1

Answer:
sin(A-B) = 24/25
Step-by-step explanation:
The trig identity for the differnce of angles tells you ...
sin(A -B) = sin(A)cos(B) -sin(B)cos(A)
We are given that sin(A) = 4/5 in quadrant II, so cos(A) = -√(1-(4/5)^2) = -3/5.
And we are given that cos(B) = 3/5 in quadrant I, so sin(B) = 4/5.
Then ...
sin(A-B) = (4/5)(3/5) -(4/5)(-3/5) = 12/25 + 12/25 = 24/25
The desired sine is 24/25.
Answer: Person A generates 107.6 millions and person B generates 85.3 millions.
Step-by-step explanation:
Let 'x' millions be the amount generated by person A then the amount generated by person B be 'x-22.3' millions.
Since they both earn together $192.9 millions.
So according to the our assumptions we have,

Therefore, the amount generated by person A=107.6 millions
And the amount generated by person B= 192.9 millions - 107.6 millions
=85.3 millions
