Answer:
a) The sequence of first three terms
5 , 8 , 13 ..
b) The of the sequence
a₁₀ = 104
<u><em></em></u>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given term of the sequence
aₙ = n² + 4
put n=1
First term a₁ = 1² +4 = 1+5
put n =2
Second term a₂ = 2²+4 = 4+4 =8
Put n=3
Third term a₃ = 3² +4 = 9+4 =13
The sequence of first terms
5 , 8 , 13 ..
<u><em>Step(ii):-</em></u>
Given term of the sequence
aₙ = n² + 4
put n =10
a₁₀ = 10²+4 = 100+4 = 104
a₁₀ = 104
The of the sequence
a₁₀ = 104

Answer:
Step-by-step explanation:
Set up the following ratio which applies to all angle bisectors and the side opposite.
8 / (x + 4) = 12 / (2x + 1) Cross multiply
8 * (2x + 1) = 12 * (x + 4)
16x + 8 = 12x + 48 Subtract 8 from both sides
16x + 8 -8 = 12x + 48-8
16x = 12x + 40 Subtract 12x from both sides
16x - 12x = 40
4x = 40 Divide by 4
4x/4 = 40/4
x = 10
Answer:
x does equal -2
Step-by-step explanation:
Substitue x = -2:
[5(-2) -2 = -12]
Simplify:
[-10-2 = -12]
Add/Subtract from left to right:
[-12 = -12]
Therefore:
x = -2
