The answer, is 40,629. multiply length times width. 43.5x934=40,629.
(hope this helps)
How you simplify fractions is figuring out what the highest number that can go into them is.
I now that's a bit confusing but I'll explain.
In this case, 2 can go into both 10 and six, (because 2×5=10 and 2×3=6) and no higher number can, so the simplified version of 6/10 is 3/5. (the numbers we multiplied by 2)
sin(x+y)=sin(x)cos(y)-cos(x)sin(y)
also, remember pythagorean rule, 
given that sin(Θ)=4/5 and cos(x)=-5/13
find sin(x) and cos(Θ)
sin(x)
cos(x)=-5/13
using pythagorean identity
(sin(x))^2+(-5/13)^2=1
sin(x)=+/- 12/13
in the 2nd quadrant, sin is positve so sin(x)=12/13
cos(Θ)
sin(Θ)=4/5
using pythagrean identity
(4/5)^2+(cos(Θ))^2=1
cos(Θ)=+/-3/5
in 1st quadrant, cos is positive
cos(Θ)=3/5
so sin(Θ+x)=sin(Θ)cos(x)+cos(Θ)sin(x)
sin(Θ+x)=(4/5)(-5/13)+(3/5)(12/13)
sin(Θ+x)=16/65
answer is 1st option
Answer:
All real numbers.
Step-by-step explanation:
25-4x=15-3x+10-x
25-4x-(-3x)-(-x)=15+10
25-4x+3x+x=25
25-x+x=25
25=25
