Yes you are correct. You take half of the x coefficient 18 to get 9, then you square 9 to get 81
x^2+18x+81 is a perfect square trinomial which factors to (x+9)^2
Answer:
5.3
Step-by-step explanation:
27.8/37 = x/7
37x = 194.6
x=5.25
x=5.3
Answer:
3, 5, 7, 9, 11, .........
Step-by-step explanation:
Given
= n(n + 2) , then
S₁ = 1(1 + 2) = 1(3) = 3 ⇒ a₁ = 3
S₂ = 2(2 + 2) = 2(4) = 8
S₃ = 3(3 + 2) = 3(5) = 15
Thus
a₂ = S₂ - S₁ = 8 - 3 = 5
a₃ = S₃ - S₂ = 15 - 8 = 7
The first 3 terms are 3, 5, 7
This is an AP with common difference d = 2, then
a₄ = a₃ + 2 = 7 + 2 = 9
a₅ = a₄ + 2 = 9 + 2 = 11
and so on
Let'sSo, we gave 2 parallel lines and 2 transversals, we have to match the angles.
Let's start with angle b,
Let's move on to angle e,
Let's move on to angle d,
Moving to angle c, we have;
And, angle a;
Answer: The answer is all real numbers
Step-by-step explanation:
This is the answer because the line goes on infinitely and will pass through all of the numbers (negative, positive). Its not y 0 because it passes through 0 when the line goes through x (side to side) axis.
