The statement regarding the expansion of (x + y)" that is correct is D. The coefficients of yn - 1 and yn – 1 both equal 1.
<h3>How to expand?</h3>
It should be noted that for any positive integer, n, the expression of (x + y)^n will be C(n,0)x^n + C+n, 1)x^n-1 .... C(n, n)y^n.
Here, the statement regarding the expansion of (x + y)" that is correct is that the coefficients of yn - 1 and yn – 1 is both equal to 1.

Answer:
A and C
Step-by-step explanation:
for A
QT/RT=ST/QT=QS/QR
There are two QT's in this
so
(QT)^2 = RT * ST
FOR B
there is no RT twice
for C
QR/RT RS/QR
There is a QR twice
so QR^2=RT*RS
FOR D there is no RT twice

Answer:
<h2>4</h2><h2>11</h2>
Step-by-step explanation:
20:5=4 (minutes for 1 meter)
4*11=44 minutes for 11 meters
or
20 : 5 = x : 11
x = 20*11:5
x = 44
or
20:5* 11=44
