3x-3/x^2-1* (x+2)(x+1)/x-1

Answers

Hello,

If x≠1 and x≠-1 then

$(3x-3)/(x^2-1)*((x+2)(x+1))/(x-1)=(3(x-1))/(x-1)*((x+2)(x+1))/((x-1)(x+1))\n=(3(x+2))/(x+1)$

I need help with the answers please....I have no idea how to do this and I'm already behind

Answers

Remember alternative exterior angles are congruent... that means for example 12 that the angles are congruent

Also, interior angles are congruent... that means for example 17 the angles are congruent (also 19)

And, vertical angles are also congruent... that means for example in 18 the angles are congruent...

Consecutive angles also are congruent... that means 14

Corresponding angles are also congruent.. that means for example 13

Any other ones that I didn't exactly list... if they look like the ones I DID list then they go under that definition...

Hope this helps :)

Your answer is congruent. (Su respuesta es congruente)

it is congruent because if the two sides are simialer then that means they fall under the congruent section.

Can someone solve the expression: 0.14 + (107.5 / 30) * 0.04?

Answers

The answer will be 0.3

To solve this mathematical expression. Here's a step-by-step solution:

1. Firstly, we have to follow the order of operations, also known as BIDMAS/BODMAS/PEDMAS: Brackets/Orders (or Parentheses/Exponents), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).

2. Look for anything in parentheses (or brackets). We have (107.5 / 30). Let's solve this division problem first. The result is 3.5833333333333335.

3. The next step would be to multiply this result by 0.04 to follow the order of operations: 3.5833333333333335 * 0.04, which equals 0.14333333333333334.

4. Lastly, add 0.14 to the result of the multiplication which we've just calculated: 0.14 + 0.14333333333333334.

5. After doing the addition, we end up with the final answer, which is 0.2833333333333333.

I hope this breakdown clarifies the process of solving this relatively complex expression! Please let me know if you have any more questions.
