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
why not just ask the question here instead? :)
Answer:
Equation: 5c + 7 = 2
Solution: The number is -1.
Step-by-step explanation:
The unknown number is c.
"the product of a number and 5" is 5c
"Seven more than the product of a number and 5" is 5c + 7
"Seven more than the product of a number and 5 equals 2" is 5c + 7 = 2
The equation is
5c + 7 = 2
To solve, we first subtract 5 from both sides.
5c + 7 - 7 = 2 - 7
5c = -5
Now divide both sides by 5.
5c/5 = -5/5
c = -1
