Answer:
D
Step-by-step explanation:
2x(x^4 + 6x^2 - 27)
x^4 + 6x^2 - 27 = 0
x^2 = y
y^2+ 6y - 27 = 0
(y+9)(y-3) = 0
(x^2+9)(x^2-3) = 0
2x(x^2-3)(x^2+9)
78 cm is the answer to your problem i hope this helps
Answer:
n=16
Step-by-step explanation:
Let's solve your equation step-by-step.
1/
2
n−3=5
Step 1: Add 3 to both sides.
1/
2
n−3+3=5+3
1/
2
n=8
Step 2: Multiply both sides by 2.
2*(
1/
2
n)=(2)*(8)
n=16
Answer:
n=16
You must get the like terms on the correct sides, so here is how to solve it:
First subtract 5x from both sides: 3x+4=-11
Then subtract 4 from both sides: 3x=-15
Finally divide by 3: x=-5
The radius is 22 for this , good luck my friend!!
