El perímetro es 28cm y el ancho es de 6 cm cuál es al alto
1 answer:
Answer:
El mayor lado del rectángulo es de 10 cm
Explicación paso a paso:
Perímetro de un rectángulo: es el doble de la suma de sus lados
P = 2 (a+b)
a: es el ancho del rectángulo
b: es el largo del rectángulo
Uno de los lados es 6cm mas que el otro lado
b= a + 6 cm
Sustituimos en la ecuación de perímetro:
28cm /2 = a+a+6cm
14cm = 2a +6 cm
14cm-6cm = 2a
a = 4 cm
b = 10cm
El mayor lado del rectángulo es de 10 cm

<u>Given</u>
- Equation 5x - y = 12
and
- Inequality 5x - y > 12
<em>See the graphs attached</em>
To draw the graphs follow the rules we described in the previous questions.
- 1. Identify x-intercept and y-intercept and connect them to have the line.
- 2. Shade the region above or below the line for the inequality.
We see the only difference the expressions have is the equation or inequality symbols.
- Equation symbol means the graph of the equation is a line.
- Inequality symbol means the graph of this is a region above the same line, in our case the line is not a part of the covered region because it is "<".
We can state that the inequality excludes the line and includes only the region above the same line.
