Answer:
Step-by-step explanation:
Greatest multiplier of 4 that is less than 21 is 5 (4 x 5 = 20)
Put the remaining number as the numerator (21 - 20 = 1)
I'm pretty sure the answer would be D because one of the properties of a rectangle is that opposite sides are congruent, and statement D shows that.

Step-by-step explanation:
3x/10-2 = x/5+2
+2 +2
3x/10 = x/5+4
x10 x10
3x = x(5 x 4)
-x -x
2x = 20
/2 /2
x=10

Step-by-step explanation:
∫ dx / (x^2√(9-x^2))
Substitute x = 3sinu and dx = 3cosu du
then the √(9-x^2) = √( 9 - 9sin^2u) = 3 cos u and u = arcsin(x/3)
= 3 ∫(csc^2 u du )/ 27
= 1/9 ∫(csc^2 u du
= -1/9 cot u
= -√9-x^2) / 9x.
