X + y = 15
x - y =3
First you have to work out what two numbers add together to make 15, for example 1 and 14 or 5 and 10.
Then you have to work out which set of numbers have a difference of 3.
The numbers would be 6 and 9.
Once you have the two numbers, multiply them together:
6 x 9 = 54
Answer:
The relationship between the lengths of the sides of the triangle is that they all follow the Pythagorean Theorem (at least I'm pretty sure that's the answer.
Step-by-step explanation:
If you plug in the smaller sides like 9^2+40^2 which equals to 1681. Then you square 1681, you'll get 41 as your hypotenuse. The sides of triangle provided above your question, should follow the formula given to you which is c^2=a^2+b^2. Just to be safe, you can check if all of the triangle sides actually are true for the Pythagorean theorem.
Answer:
8.
Step-by-step explanation:
As seen in the pattern y seems to be two times x so 4 x 2 = 8.
Hope that helps
