The answer would be C6.
so we know the perimeter is 36 and the function for perimeter is 2L + 2W=P.
we also know that two times w length
so we take 6 * 2 equals 12 + 12 * 2 which equals 24 + 12 + 36 because 12 * 3 is 36.
answer
( -2,4 )
- A rectangle is made of four sides with opposite sides of equal length. Using the y-coordinates of the first two points, the side is 5 - ( - 2 ) = + 7
units long in the x-direction
Using the x-coordinates of the last two points, the side is 4 -2 = + 2
units long in the y-direction.
Subtracting 7 units from the last point, the result
( 5 - 7 , 4 ) = ( -2,4 )

Answer: x^2 + 6x – 7 = 0
The solutions x = -7 and x = 1 can be written as:
(x+7)(x-1) = 0
(Because you find the solution values for x from the brackets e.g (x+7) to get x=-7, dunno how to explain it better sry)
From which you can expand the brackets and find the answer in quadratic form.
(x+7)(x-1) = 0
Expand the brackets
x^2 + 7x – x – 7 = 0
x^2 + 6x – 7 = 0
Resolviendo un sistema de ecuaciones, vemos que se venden 6 libros de secundaria 4 y 6 libros de secundaria 1.
<h3>
¿Como escribir un sistema de ecuaciones?</h3>
Primero definimos dos variables:
- x = numero de libros de secundaria 4 vendidos.
- k = número de libros de secundaria 1 vendidos.
Sabemos que se venden 12 libros en total, entonces:
x + k = 12
Tambien sabemos que se recauda un total de $82, entonces:
x*$8 + k*$6 = $82
Entonces tenemos dos ecuaciones.
a) Usando la primer ecuacion, podemos aislar x para tener:
x = 12 - k
b) Ahora podemos reemplazar eso en la otra ecuación para solucionar el sistema.
(12 - k)*$8 + k*$6 = $82
$96 - $2*x = $82
$2*x = $12
x = $12/$2 = 6
Es decir se venden 6 libros de secundaria 4, y como se venden 12 libros en total, los otros 6 libros vendidos son de secundaria 1.

Answer:
16x² + 64x + 64
Step-by-step explanation:
Given
A = 16x²
Increasing the sides by 2, substitute x = x + 2 into A
A = 16(x + 2)² ← expand factor using FOIL
= 16(x² + 4x + 4 ) ← distribute
= 16x² + 64x + 64
