Answer:

number 11 is slope=3, then number 12 is slope=-2, then number 13 is slope=4 and number 14 is slope =1. i got my answers by looking at the x axis. In a y=mx+b whatevers infront of the x is your slope. idk what 15 is though its weird lol Good luck! :)

Answer:

8x2y - 6x2 - 8xy2 - y2

Step-by-step explanation:

Equation at the end of step 1 :

(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+(8x•(y2)))-3y2)

Step 2 :

Equation at the end of step 2 :

(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+23xy2)-3y2)

Step 3 :

Equation at the end of step 3 :

(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-3y2)-(x2+8xy2-2y2)

Step 4 :

Equation at the end of step 4 :

(((((5•(x2))•y)-(5•(x2)))+3x2y)-3y2)-(x2+8xy2-2y2)

Step 5 :

Equation at the end of step 5 :

(((((5•(x2))•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)

Step 6 :

Equation at the end of step 6 :

((((5x2•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)

Step 7 :

Final result :

8x2y - 6x2 - 8xy2 - y2

Answer:

1. 38, 80, 89 and 4. 14, 15, 29

I don't know if there is supposed to be only one, but both of those do not form right triangles.

Step-by-step explanation:

Evaluate all of them and see if they meet the requirements of the Pythagorean Theorem, a² + b² = c².

1. 38, 80, 89

a² + b² = c²

38² + 80² = 89²

1444 + 6400 = 7921

7844 ≠ 7921.

This is an answer because it doesn't satisfy the Pythagorean Theorem.

2. 16, 63, 65

a² + b² = c²

16² + 63² = 65²

256 + 3969 = 4225

4225 = 4225

This isn't the answer because it satisfies the Pythagorean Theorem.

3. 36, 77, 85

a² + b² = c²

36² + 77² = 85²

1296 + 5929 = 7225

7225 = 7225

This isn't the answer because it satisfies the Pythagorean Theorem.

4. 14, 15, 29

a² + b² = c²

14² + 15² = 29²

196 + 225 = 841

421 ≠ 841

This is an answer because it does not satisfy the Pythagorean Theorem.

What's the answer for the attachment

gulaghasi [49]

ABC is not a right angled triangle

Solution:

Given that, Triangle ABC has perimeter 18 cm

AB = 7 cm

BC = 3 cm

We have to find whether ABC is a right angled triangle

Let the sides of triangle be AB, BC, AC

Perimeter of triangle is given by formula:

perimeter = sum of length of all three sides of triangle

18 = AB + BC + AC

18 = 7 + 3 + AC

AC = 18 - 10

AC = 8

Thus the length of sides of triangle are:

AB = 7 cm

BC = 3 cm

AC = 8 cm

For a triangle to be right angle, it must satisfy the pythagoras theorem

Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

The longest side of triangle is hypotenuse

Therefore, AC = 8 cm is the hypotenuse

Thus by above theorem we get,

$AC^2 = AB^2+BC^2$

Substituting the values we get,

$8^2 = 7^2 + 3^2\\\\64 = 49 + 9\\\\64 \neq 58$

Thus the pythagoras theorem is not satisfied

Thus ABC is not a right angled triangle

PLEASE HELP!!! I️ GOTTA RAISE MY GRADE!! Find the discount on a leather recliner with a regular price of $250 if the recliner is

AlekseyPX

I’m pretty sure the answer is $200 because %20 of 250 is 50 so you subtract 50 from 250
