Answer:
9x sqrt 5x
Step-by-step explanation:
Simplify the radical by breaking the radicand up into a product of known factors.
9x√
5x
Answer: 2=x
Step-by-step explanation:
4x-1 + 2x-1 = 5x
First combine like terms together
4x-1 + 2x-1 is 4x+2x-1-1
4x+2x-1-1 =6x-2
4x-1 + 2x-1=6x-2
6x-2=5x
The oppisite of 6x is -6x so -6x on both sides of equation to keep it balanced
6x-6x-2=5x-6x
0-2=-1x
-2=-1x
Divide both sides of the equation by -1 since -1 is being multiplied by x and the oppisite of multiply is divide
-2/-1=-1x=-1
2=x
Answer:
yes
Step-by-step explanation:
Answer:
80
Step-by-step explanation:
From the given diagram;
KN = NM
9x - 5 = 7x + 7
9x - 7x = 7 + 5
2x = 12
x = 12/2
x = 6
Since KM= 2KL
KM = 2(6x+4)
KM = 12x + 8
KM = 12(6)+8
KM = 72+8
KM = 80
Hence the length of KM is 80
