3 x 7 = 21
0
11x - 21 = 7x + 3 4x = 24x = 6
y=3, and y=-3. 6y² - 54 = 0 factors to 6(y² - 9) = 0 --> 6(y + 3)(y - 3) = 0
The solution (not sum) to the equation 21 = 3c + 6 is as follows:21 = 3c + 621 - 6 = 3c + 6 - 615 = 3c3c = 153c/3 = 21/3c = 7
3p2 - 21p + 35 = 0 Then p = [21 +/- sqrt(212 - 4*3*35)]/(2*3) = [21 +/- sqrt(441-420)]/6 = [21 +/- sqrt(21)]/6 = 2.736 and 4.264
6
x2-4x-21 = 0 => x = -3 or x = 7 x2-3x-18 = 0 => x = -3 or x = 6
m = 6
21/3 does.
If: 3x-3 = 7x+21 Then: x = -6
(0, -3), (2, 0), (4 ,3)
y = 6/7x+3 General form of the line equation: 6x -7y+21 = 0
3 x 7 = 21
3 + 3 + 3 + 1 + 11 = 21
-a^2- 9a - 18 = 0 -(a^2 + 9a + 18) = 0 -(a + 6)(a + 3) = 0
6 or it equals butterfly with one of the 3's backwards and then the 0 and then the other 3
