Answer:

D - x = 19 x = -17

Step-by-step explanation:

Factor the equation to make the problem easier - you should have this:

(x - 18) (x + 18) = 1

Set each binomial to 1:

x - 18 = 1

x + 18 = 1

This should give you x = 19 and x = -17

Consider the rational number, −0.4. Is the number greater than −2 and 1/3 but less than 4/5 ?
8_murik_8 [283]

Answer:

No

Step-by-step explanation:

Since the rational number -0.4 is a negative, it cannot have a greater value than 1/3 since it is a positive.

Though, the rest of the sentence is true.

-0.4 > -2

-0.4 < 4/5

a = 6 and b = 8

6² + 8² = c²

36+64 = c²

100 = c²

c = √100

c= 10

The nth term of a sequence is given by 3n² + 11 Calculate the difference between the 6th term and the 9th term of the sequence.​
katovenus [111]

The difference between the 6th term and the 9th term of the sequence is 135

<h3>How to determine the difference</h3>

Given that the nth term is;

3n² + 11

For the 6th term, the value of n is 6

Let's solve for the 6th term

= 3( 6)^2 + 11

= 3 × 36 + 11

= 108 + 11

= 119

For the 9th term, n = 9

= 3 (9)^2 + 11

= 3( 81) + 11

= 243 + 11

= 254

The difference between the 6th and 9th term

= 254 - 119

= 135

Thus, the difference between the 6th term and the 9th term of the sequence is 135
