no they are both incorrect by my understanding of your question use the Pythagorean theorem a^2 + b^2 =c^2 therefore 7^2 +x^2 = 13^2 or 49+x=169 then solve normally 169-49=120  √120 =5


The answer is  5

Sheridan is correct.  She followed all of the correct steps of the Pythagorean Theory.  The reason that Jayden was wrong is because he used the hypotenuse of the triangle as "b" in the formula instead of using it as "c" which is where they hypotenuse always has to go in this formula.

4. You have 36 pairs of running shoes. Let x be the
Liono4ka [1.6K]

Answer:

  • Nikes: 24 pairs
  • Adidas: 12 pairs

Step-by-step explanation:

The system of equations can be written ...

  x + y = 36

  x = 2y

__

The system can be solve by substituting for x:

  (2y) +y = 36

  y = 12 . . . . . . divide by 3

  x = 2(12) = 24

There are 24 pairs of Nikes and 12 pairs of Adidas.

Why is using a compass and straightedge and compass better than technology
Dimas [21]

Technology comes from the Greek root \tau \epsilon \chi, meaning art or craft.


For the Greeks, a straightedge and compass was technology.


The nice thing about a straightedge and compass construction of any length is that there's always a corresponding algebraic form consisting of natural numbers combined via addition, subtraction, multiplication, division and square rooting (of positive numbers). So we get an "exact" answer, at least using radicals.


Compare that to the typical calculating technology we use today where the square roots turn into approximations. The calculator is worse, turning an exact answer into an approximation.


Straightedge and compass constructions play a large role in the development of mathematics but they're not really better, it's just how things went. By restricting ourselves to straightedges (linear equations) and compasses (circles, quadratic equations) we restricted the possible lengths we could construct. Understanding exactly how propelled mathematics forward for a couple of thousand years.
