20 = 400
Yes.
205
A equals 20.
10 plus 20 plus 30plus 40 plus 50 equals 150 because 50 plus 40 equals 90 plus 30 =120+20= 140 then + 10 = 150
(3x-4)(x+5)
(20 - x)/5
20
To solve for x, we'd have to know what this expression equals.
y=16 x= -4
-7m + 20 = -17m - 1010m = -30m = -3
68
-3x + 5 = 20 -3x = 15 x = -5
Better formatting is cos(2x+20)=-0.5
20 = 400
(x + 4)(3x - 5)
(3x - 5)(x + 4)
