Answers

Answer:

Step-by-step explanation:

By using the substitution method the solution to the given equation is

x = ±7/2 + √5/2

System of equation

Given the equation expressed as:

(2x +3)^2 + 8(2x + 3) + 11 = 0

Expand the equation

4x^2 + 12x + 9 + 16x + 24 + 11 = 0
4x^2 + 28x + 44 = 0
x^2 + 7x + 11 = 0

Factorize the result to have:

On factorizing the values of x are

x = ±7/2 + √5/2

Sherry thinks 7, 7 and 12 are side lengths of a right triangle. Do you agree or disagree? Justify your reasoning. PLEASE NOW!!!! PLEASE!!!!!!

Answers

Answer:

disagree

Step-by-step explanation:

If the triangle is right, then the square of the longest side must equal the sum of the squares on the other 2 sides.

longest side = 12 ⇒ 12² = 144

7² + 7² = 49 + 49 = 98

Since 144 ≠ 98 then triangle is not right

Name a possible value for n that is a solution to 15 < n, but not a solution to n < 25.

PLEASE EXPLAIN WHY ITS THAT ANSWER

Answers

Answer:

Step-by-step explanation:

The number has to be greater than 15 but not less than 25 so any number that is at least 25 works.

Answer:

It would just be at least 26. Because, it's saying that n has to be greater than 15 and greater than 25. so, that the n < 25 is wrong. So i would put 26 because 15 < (is less than) 26, and 26 <(less than) 25 is wrong which is required to be an answer. So you could do 26 through infinity.
