Answer:
x=5/2, y=0 & x=5, y=5. So the answer is C).
Step-by-step explanation:
2x^2-13x+20=2x-5
2x^2-13x-2x+20-(-5)=0
2x^2-15x+20+5=0
2x^2-15x+25=0
factor out the trinomial
(2x-5)(x-5)=0
zero property
2x-5=0, x-5=0
2x=0+5=5, 2x=5, x=5/2
x=0+5=5
y=2(5/2)-5=5-5=0
y=2(5)-5=10-5=5
By arranging the numbers in ascending order we get,
2, 2, 6, 9, 9, 11, 11, 12, 32, 43, 46, 54, 54, 59
The 2 middle numbers are:
11, 12
To find the median we have to add them and divide them by 2
So, (11+12)÷2
23÷2
11.5
A.60/100=3/5
B.10-8=2
D.20/100=5
C.0.37=
E.5/6=0.83
width = 11, len = 19
length = 2w - 3
l = length
w = width
2(length) + 2(width) = perimeter
2(2w - 3) + 2(w) = 60
6w -6 =60
w = 11
len = 2(11) - 3
