Answer 1

Answer:

Answer: $x^(-6)=(1)/(x^(6))$

Step-by-step explanation:

There is a rule in mathematics related to negative exponents:

A number with a negative exponent is equal to the inverse of the number raised to that exponent, but positive.

To understand it better:

The exponent of a number, when positive, tells us how many times we should use that number in a multiplication.

Now, when the exponent is negative, the opposite operation to multiplication must be performed: division.

For example, if we have the following:

$x^(-6)$

We have to write the inverse of $x$ , which is the base, to the power of $6$ :

$x^(-6)=(1)/(x^(6))$

I'm in year 9 in England and I got this question. I have no idea what to do

Answers

sum of two consecutive terms is 145
let the numbers be the nth and (n+1)th term

nth term = 5n+10
(n+1)th term = 5(n+1)+10 = 5n+5+10 = 5n+15

5n+10 + 5n+15 = 145
⇒ 10n + 25 = 145
⇒ 10n = 145-25 = 120
⇒ n = 120/10 = 12

terms are:
5n+10 = 5 x 12 + 10 = 70
5n + 15 = 5 x 12 + 15 = 75

Answer:

Area = 108 square units.

Step-by-step explanation:

If you want to find the area of a triangle, the formula is 1/2 base times height. That would be 1/2 of 18 times 12. That is 9 times 12 which is equal to 108. (Don't forget the units) Please mark me brainliest! I hope this helps!
