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

Step-by-step explanation:
Answer:
167 degrees Fahrenheit
Step-by-step explanation:
I think you mean:
We have C=75 so replace C with 75:
"Isolate the constant by adding 7 to both sides of the equation."
This step separates the non-squareable 7 and the squareable
.
"Add 9 to both sides of
to form a perfect square trinomial while keeping the equation balanced."
After separating the non-squareable, add the number which makes the first or left side a perfect square trinomial. The formula to find the number is:
.
When we plug the values:
Simplify:
"Write the trinomial
as
squared."
When you factor
, you will get
.
"Use the square root property of equality to get
."
The 16 is coming from the part when we add 9. We needed 9 on the left side for a perfect square, but to protect the balance of the equality, we need to add 9 to the right side too. When we add 7 and 9, we got 16, and that is where it came from.
"Isolate the variable x to get solutions of -1 and 7."
To isolate x we branched the plus-minus sign:
