Step-by-step explanation:
Answer:
1.=x+5
2.=x+11
3.=x+2
4.=2x+3
Step-by-step explanation:
3+x+2
=3+x+2
=(x)+(3+2)
=x+5
7+x+4
=7+x+4
=(x)+(7+4)
=x+11
Answer:
that's 4 and 7 .............
Answer:
this is easy just do 12-(-8)= 12+8=20
so the answer is 20
Step-by-step explanation:
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
