Answer:
5x +4y
Step-by-step explanation:
The perimeter of a triangle is the sum of side lengths. That fact can be used to find z, the length of the third side.
(2x +3y) +(5x -2y) +z = 12x +5y . . . . sum of sides is perimeter
z = (12x +5y) -(7x +y) . . . . . . . . . . . . subtract (7x+y) from both sides
z = 5x +4y . . . . . . . . . collect terms; the length of the third side
The third side of the triangle is (5x +4y).
Answer:A
Step-by-step explanation:
0=-2x^2+x+3
-2x^2+x+3=0
a=-2 b=1 c=3
Answer:
15
Step-by-step explanation:
If this is an arithmetic progression, then there is a common difference.
-3-18 = -21
-21/3 = -7
18 - 7 = x
x = 11
11 - 7 = y
y = 4
4 - 7 = -3
x + y
11 + 4 = 15
Answer:
it might be 48.9 but im not sure
Step-by-step explanation:
Answer:
Decreases
Step-by-step explanation:
As 'n' increases the value of the (1/4) will decrease.
Say, n=1 ; 1/4
n=2 ; 1/4 * 1/4 = 1/16(because n=2, there are two 1/4s)
n= and so on
