Answer:
The value of T₂₀ - T₁₅ is <u>-20</u>.
Step-by-step explanation:
<u>Given</u> :
<u>To</u><u> </u><u>Find</u> :
<u>Using Formula</u> :
General term of an A.P.
- >> Tₙ = nᵗʰ term
- >> a = first term
- >> n = no. of terms
- >> d = common difference
<u>Solution</u> :
Firstly finding the A.P of T₂₀ by substituting the values in the formula :
Hence, the value of T₂₀ is a + 19d.
Secondly, finding the A.P of T₁₅ by substituting the values in the formula :
Hence, the value of T₁₅ is a + 14d
Now, finding the difference between T₂₀ - T₁₅ :
Hence, the value of T₂₀ - T₁₅ is -20.
X = 1 is the correct answer.
Using the log properties, remember that Log(base2)2 = 1
3log(base2)2x = 3
divide both sides by 3
log(base 2)2x = 1
log(base2)2 = 1
1 * x = 1
x = 1
Answer:
area=6
perimeter=36
Step-by-step explanation:
With the number being x, we have 3x^2>6(x/9). Expanding, we get 3x^2>6x/9 and 3x^2>2x/3. Dividing by x, we get 3x>2/3 and dividing by 3 we get x>2/9
a+2 a +1
= ------- / ------------------
a -5 (a - 3)(a - 5)
a+2 (a - 3)(a - 5)
= ------- * ------------------
a -5 a +1
(a+2)(a - 3)
= ----------------
a +1
a NOT equal 5 and -1
