Answer: 6, 8, 10, 12
Step-by-step explanation:
Given that x is the number, the 4 numbers would be
x, x + 2, x + 4, x + 6
so the two smallest numbers would be x and x + 2
and the two largest numbers would be x+4 and x+6
now set up an equation
x(x+2) = (x+4)(x+6) - 72
now FOIL
x^2 + 2x = x^2 + 6x + 4x + 24 - 72
combine like terms
x^2 + 2x = x^2 + 10x -48
subtract x^2 from both sides
2x = 10x - 48
subtract 2x from both sides
0 = 8x - 48
add 48 to both sides
48 = 8x
divide both sides by 8
6 = x
so the four numbers, x, x+2, x+4, and x+6 when you plug in x are equal to
6, 8, 10, 12
Answer:
y=4x
Step-by-step explanation:
The line goes through the points (0, 0) and (2, 8).
You can plug these in to the slope formula, and the slope is 4
Since the line intersects the y-axis at 0, the y-intersect is 0.
Using these two pieces of information, you now know that the equation is
y=4x+0, or y=4x.
Hope this helps!

Step-by-step explanation:
Answer:
94
Step-by-step explanation:
(Lo siento, español no es mi primero lingua, pero intentaré mi mejor :) )
La ecuación is (66 + 90 + x + 94)/4 = 86
Multiple los dos de los lado por 4.
66 + 90 + x + 94 = 344
Hace 66 + 90 + 94, y ponelos a la otro lado con sustracción.
X = 94
94 es la tercera lecture.
