X^4 - 3x^2 + 2
= (x^2 - 1)(x^2 - 2)
Note that x^-1 is the difference of 2 squares:-
= (x + 1)(x - 1)(x^2 - 2) Answer
Step-by-step explanation:
2x + 6=2(x+3)
2x+6=2x+6
4x=0
x=0/4
No answer/no solution
Answer:
<h2><u><em>
a = 17°</em></u></h2>
Step-by-step explanation:
it is a parallelogram, the opposite angles are the same size
so
4a + 64 = 8a - 4
64 + 4 = 4a
68 = 4a
a = 68 : 4
a = 17
Answer:
$n + $20
Step-by-step explanation:
Jim already has $n, and his mom has given him $20. We know we are not taking $n and subtracting $20, since his mom is adding that on to what he already has, we know we are not dividing, not multiplying but adding.
Conclusion : To find how much money he has now you would use the expression $n + $20

The length of segment A.F in the circles given is: 62 units.
<h3>What is the Radius of a Circle?</h3>
A radius of a circle is half the diameter of a circle, which is a point from the center to any point on the circumference of the circle. This implies that any segment that is drawn from the center of a circle to any point on the circumference of a circle is a radius. Also, all radii of a circle are always congruent to each other.
Radius of circle B = AB = BD = 24 units [all radii of a circle are congruent to each other].
Radius of circle E = CE = EF = 9 units [all radii of a circle are congruent to each other].
CD = 4
DE = x
CD + DE = CE
Plug in the values into the equation
4 + x = 9
x = 9 - 4
x = 5
DE = 5
The length of segment DE is 5 units
A.F = AB + BD + DE + EF
Plug in the values into the equation
A.F = 24 + 24 + 5 + 9
A.F = 62 units.
Therefore, the length of segment A.F in the given circle is determined as: 62 units.
