Answer:
10 and 19
Step-by-step explanation:
- In Algebra, an even number = 2x, because anything multiplied by 2 is even.
- There are two numbers in the question, I'll define the first one as 2x
- the other number is 1 less than twice of the first, so I'm going to define it <u>in algebra as 2(2x) - 1</u>, which is just 4x - 1
- the square of the first is

- the square of the second is

- add them together:

- this equation = 461, so

- simplify to

- I wont explain how to solve this here, since it is very complicated, if you don't know search up solving quadratics.
- the <u>solutions are 5 or -4.6</u>, it cannot be -4.6 since the question says positive, so the solution for <u>x = 5</u>
- substitute x into our equations for the two numbers in steps 1 and 2
- the <u>first number = 10, the second = 19</u>
This is the formula of finding the hypotenuse: a² + b² = c².
So the legs would be a and b.
4² + 4² = c²
c² = 16 + 16
c² = 32
c = √32 (Option C)
Answer:
(18,−21)
Step-by-step explanation:
Dilation: multiply each coordinate
(x,y)\rightarrow (3x,3y)
(x,y)→(3x,3y)
Dilations multiply by scale factor
(\color{red}{6},\color{blue}{-7}) \rightarrow (3\cdot \color{red}{6},3\cdot \color{blue}{-7})=\mathbf{(18,-21)}
(6,−7)→(3⋅6,3⋅−7)=(18,−21)
