Answer:
2/3
Step-by-step explanation:
I assume the 2 after the j is a square. So, we bring the 21 to the other side by subtracting it from both sides, getting 144j^2=64. Now we divide to get 64/144 = j^2. Make sure NOT to simplify it, it's perfect right now. The square root of that is 
, or 8/12, which we can now simplify to 2/3. Hope this helps!
Answer:
The value of k is -11
Step-by-step explanation:
If (x+2) is a factor of x3 − 6x2 + kx + 10:
Then,
f(x)=x3 − 6x2 + kx + 10
f(-2)=0
f(-2)=(-2)³-6(-2)²+k(-2)+10=0
f(-2)= -8-6(4)-2k+10=0
f(-2)= -8-24-2k+10=0
Solve the like terms:
f(-2)=-2k-22=0
f(-2)=-2k=0+22
-2k=22
k=22/-2
k=-11
Hence the value of k is -11....

Answer:
The perimeter of the shape is of 40.56 units.
Step-by-step explanation:
Perimeter of a shape:
The perimeter of a shape is the sum of the lengths of all its sides.
In this question:
The sides are a = 9.60, b = 9.33, c = 4.46, d = 8.56, e = 8.61.
So
The perimeter of the shape is of 40.56 units.
