Answer:
XY = 10 cm
Step-by-step explanation:
XY is a midsegment and is half the length of the 3rd side DE, that is
XY = 
DE = × 20 = 10 cm
There will be 73 apples in each basket,
to solve this you divide 219 into three.
Hope this helped!!
Answer:
The relationship between these terms may be sums or difference. You call an expression with a single term a monomial, an expression with two terms is a binomial, and an expression with three terms is a trinomial. An expression with more than three terms is named simply by its number of terms. Plz give brainiest

<span>my answer to you would be that for this kind of a sequence, there is a fixed way of finding the nth term value
let's get these basics straight first:
1) Un= the nth term value
for eg. U1 = 1st term value
2) a = first term
3) d = difference
Ok now the first step to finding the nth term is finding the constant difference
in the example that you gave the constant difference is 1.5
ie 1.5 is being added on each time
now the fixed rule for finding the nth term is :
Un = a + d(n-1)
why?
because let's take a common example of a linear sequence, a sequence with a constant first term ( so called because it forms a line when drawn in a graph):
first term is a so,
a, a+d, a+2d, a+3d......a(n-1)d
(because the coefficient of d is one less than the term number)
so putting this into your q:
a = 5.5
d=1.5
Un=a + d (n-1)
Un=5.5 + 1.5(n-1)
Un=5.5 + 1.5n - 1.5
Un=4+ 1.5n
there you go it works...
for other types like quadratic cubic and geometric progression, its a totally different story
