Answer:

5 miles per hour

Step-by-step explanation:

I made 1/20 to 3 min

1/4 to a mile so x4 both 1/4 and 3 = 12

thats 1 mile per 12 min

60 min divided by 12 equals 5 miles per hour

Complete the square to solve the equation below
frutty [35]
x^2+x= \frac{7}{4}

Take one-half of the coefficient of x and square it, then add it to both sides.

x^2+x+ (\frac{1}{4}) =\frac{7}{4}+ (\frac{1}{4})

x^2+x+(\frac{1}{4})= 2

\left(x+\frac{1}{2}\right)^2=2

x+\frac{1}{2}=\pm \sqrt{2}
-----------------------------------------------------------------
x+\frac{1}{2}=- \sqrt{2}
x=-\frac{1}{2}- \sqrt{2} <=

AND

x+\frac{1}{2}= \sqrt{2}
x= \sqrt{2}-\frac{1}{2} <=

Mademuasel [1]

Answer:

1. D. Teorema.

2. A. Axioma.

Step-by-step explanation:

En matemáticas, un conjunto de proposiciones que deben estar respaldadas por una prueba adecuada basada en el razonamiento se denomina teorema. Se puede demostrar plenamente que todos los teoremas matemáticos son verdaderos mediante el razonamiento.

Sin embargo, un axión es evidente por sí mismo y no necesita ser probado. Es un hecho ya establecido.
