Answer:

common difference = 6.

Step-by-step explanation:

Given : 2, 8, 14, 20, 26, ......

To find : What is the common difference between successive terms in the sequence.

Solution : We have given that 2, 8, 14, 20, 26, ......

Common difference (d) = $a_{2} - a_{1}$ .

Where , $a_{2}$ . = any term other than first term

$a_{1}$ . = previous term.

Then common difference = 8 - 2 = 6.

14 - 8 = 6.

20 - 14 = 6.

Therefore, common difference = 6.

Solve for x in the equation x^2-4x-9=29? x=2+/- squareroot 42 x=2+/-squareroot 33 x=2+/-squareroot 34 x=4+/-squareroot 42

jeka57 [31]

For this case what we must do is to use the formula of the resolvent in the following way:
x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
Where,
a = 1
b = -4
c = -38
Substituting the values:
x = (- (- 4) +/- root ((- 4) ^ 2 - 4 * 1 * (- 38))) / (2 * 1)
x = (4 +/- root (168)) / 2
x = (2 +/- root (42))
Answer:
x = 2 +/- squareroot 42

Simplify the product.

liberstina [14]

The value of the product expression is –6p^3 + 8p^2 – 10p

<h3>How to simplify the product?</h3>

The product expression is given as:

2p(–3p2 + 4p – 5)

Rewrite properly as:

2p(–3p^2 + 4p – 5)

Remove the bracket

2p * –3p^2 + 2p * 4p – 2p * 5

Evaluate the products

–6p^3 + 8p^2 – 10p

Hence, the value of the product expression is –6p^3 + 8p^2 – 10p

9n-10n=-3. What is the answer

Mumz [18]

Answer: n=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

9n−10n=−3

9n+−10n=−3

(9n+−10n)=−3(Combine Like Terms)

−n=−3

−n=−3

Step 2: Divide both sides by -1.

-n/1 = -3/-1

n = 3
