A geometric sequence is one that is multiplied by the same number, and an arithmetic sequence is one that is added by the same number.
2 * 2 = 44 * 2 = 8 - This works, so will be geometric
Answer: 1.032
1.29/1.25 = 1.032
Answer:
x = sqrt(11)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the sides and c is the hypotenuse
x^2 +(sqrt(5))^2 = 4^2
x^2 +5 = 16
x^2 =16-5
x^2 = 11
Taking the square root of each side
x = sqrt(11)
16x²-49=
(4x)²-7²=
(4x-7)(4x+7)
Here I have used the expression:
a²-b²=(a-b)(a+b)
Answer:
x=8 is a true solution of the radical equation
Step-by-step explanation:
we have

Solve for x
squared both sides

Convert to factored form

The solutions are x=2 and x=8
<u><em>Verify the solutions</em></u>
For x=2
Substitute in the original equation

----> is not true
therefore
x=2 is not a true solution of the radical equation
For x=8
Substitute in the original equation

----> is true
therefore
x=8 is a true solution of the radical equation
