Answer:
no.3
Step-by-step explanation:
(3x+2)(2x-8)
6x^2 - 24x + 4x - 16
6x^2 - 20x - 16
Answer:
Yes. -4 is the solution to the equation.
Explanation:
2 + 4(-4) = - 14
2 + (-16) = - 14
2 - 16 = - 14
- 14 = - 14
Answer:
1+pi/2, 5/2, square root of 12-1, 2.25. Let me know if this is correct!
Step-by-step explanation:
The slope of a line is given by the change in y coordinates over the change in x coordinate.
The slope of line DE will be (4 - -3)/ (7-1) = 7/6
If M1 and M2 are slopes of two perpendicular lines at a point then
M1× M2 = -1
Thus, the slope of a perpendicular to line DE will be -6/7.
Step-by-step explanation:
45% of number = 180
=> 100% of number = 180 * (100/45) = 400.
Hence the number is 400.
