the number is represented by "x"
8+ 4x= 4
-8 -8
4x=-4
4 4
x=-1
Check: 8+ 4( x)= 4
8+ 4(-1)= 4
8+ (-4)= 4
8-4= 4
-1
(-4) + (+8) is +4
Say the number was 4, you plus it by 5 so it is 9, times it by 8 and you got 72. for the 'and a number' you would have to be more specific Drink coke not pepsi
8n +3
NO
It is: 8x^2 +68x +32
(2x - 8)(-4x + 4) = -8x2 + 40x - 32
two real numbers, whose sum is 8 and product is max, are 4,4. 4+4=8 and 4*4=16.
8x + 8 = 4x 4x + 8 = 0 4x = -8 x = -2
abs(y^3 - 4) < 8*y
Because the product of 4 and 8 is less than either number, so it can't be a multiple, common or otherwise.
3x + (-4) ≥ 2x + 8
