What is 7 x 8 4 out of 7?
x+8=-4
How many 7 digit numbers can be formed using digits 0 to 7 when 0 is never first?
If digits can't be repeated, then there are (7 x 7 x 6 x 5 x 4 x 3 x 2) = 35,280If digits can be repeated, then there are (7 x 8 x 8 x 8 x 8 x 8 x 8) = 1,835,008
The sum of two integers is -8 and their product is plus 7 what are the two integers?
short answer -1 and -7 long worked answer let x = one of the integers let y = the other integer x+y = -8 xy = 7 solve for y y = -8 - x plug y in x(-8 - x) = 7 rearrange -x^2 - 8x - 7 = 0 divide both sides by -1 x^2 + 8x + 7 = 0 factor (x + 7)(x + 1) = 0 x = -1, -7 y = -8 - x so y = -8 + 1 = -7 or -8 + 7 = -1 so when x = -1, y = -7 when x = -7, y = -1
What is the product of -2 and -4 and -7 and -8?
-2 x -4 x -7 x -8 = 448
What is 7 x 8?

What is x when you divide x by 8 minus 4 when it equals 7?
X/8-4=7 X/8=11 X=11 x 8 X=88 ;-)
What is x if sqrt of x plus 8 equals 7?
If √x + 8 = 7, then √x = -1, so x does not exist, because √ only refers to positive roots.If √(x + 8) = 7, then x + 8 = 49 and x + 41.

8(x - 7)
How can you use 4 x 7 to find 8 x 7 find the product?
Double 4 x 7 to find 8 x 7.
What is x when f of x equals -7 and f of x is defined to be 2x plus 8?
f(x) = 2x + 8 f(x) = -7 → 2x + 8 = -7 → 2x = -15 → x = -7½ = -7.5
