Line B is incorrect cause he did not do like terms
Answer:
AX = 20
AY = 15
Step-by-step explanation:
The perimeter is ...
P = AC +CB +BA = (AX +XC) +CB +(BY +YA)
128 = AX +32 + 37 +24 +AY
35 = AX +AY
The ratios of corresponding sides are proportional:
AX/AY = XC/YB = 32/24 = 4/3
This tells us ...
AX = 4/3·AY
Substituting, we get ...
35 = (4/3)AY +AY = (7/3)AY
(3/7)·35 = 15 = AY
AX = 35 -AY = 20
The side measures are AX = 20, AY = 15.
Answer:
Step-by-step explanation:
Let us assume there are n people in the group. If possible let each have different number of friends.
Number of friends can vary from 0 to n-1 only since no one is a friend of him- or herself, and friendship is symmetrical—if x is a friend of y then y is a friend of x.)
Now n people have friends as 0,1,2...n-1 such that each has distinct number of friends.
But say if A has 0 friends, it means A has no friend,
but there is one B who has n-1 friends i.e. all the others in the party are friends to him including A
This is a contradiction. So it follows in any group of people, two of them have the same number of friends in the group.
= (4x^3y^4)/(-8xy^2)
simplify exponents by subtracting the denominator exponent from numerator exponent [x^(3-1)]
= (4x^3y^4)/(-8xy^2)
simplify -4/8 by 4 into numerator and denominator
= (-1x^2y^2)/2
= (-x^2y^2)/2
ANSWER: (-x^2y^2)/2
Hope this helps! :)
