Step-by-step explanation:
The diagonals of a parallelogram divide each other into two equal parts.
Answer:
500
Step-by-step explanation:
510=x+.21x-.19x
510=(1+.21-.19)X
510=1.02X
X=510/1.02
X=500
Answer:
x^2+2xy+y^2
Step-by-step explanation:
(x + y)(x + y)
FOIL
first x*x = x^2
Outer x*y = xy
inner: y*x = xy
last y*y = y^2
add together
x^2+xy+xy+y^2
Combine like terms
x^2+2xy+y^2
You can divide 950 by 19 to get the speed in ft/min:
950/19 = 50 ft/min
Hope this helps! :)
Answers:
k-3/4= 10
move -3/4 to the other side
sign changes from -3/4 to +3/4
k-3/4+3/4= 10+3/4
k= 10+3/4
find the common denominator for 10. Pretend that 10 has a denominator which is 1.
The common denominator is 4. Mutiply by 4 for 10/1
10(4)= 40
1(4)= 4
k= 40/4+ 3/4
k= 43/4 and k= 10 3/4
9+t/12=3
mutiply both sides by 12
12(9)= 108
t/12*12- cross out 12 and 12, divide by 12 and then becomes t
3(12)=36
108+t=36
move 108 to the other side
108-108+t= 36-108
t= -72
