Answer:
4
Step-by-step explanation:
Divide the coefficient of the x term by 2, then square the result. This number will be added to both sides of the equation. For the quadratic equation x2+4x=96, the coefficient of the x term is 4.
Answer:
50
Step-by-step explanation:
First write the equation
3/n = 5
Multiply both sides by n
3/n * n = 5 * n
Simplify
3 = 5 * n
Divide both sides by 5
3/5 = 5 * n/5
Simplify
3/5 = n
Divide
0.6 = n
So 3/0.6 = 5
The circumference formula is
C=Diameter x π=22 x π, the area formula is A=<span>π x R²
or R=</span><span>D/2=22/2=11
the answer is </span><span>d. C = 22π; A = 121π</span>
