9 tens because 10 time 9 is 90 and 2 ones
2x^2 + 5x - 12 = 0
2x^2 + 8x - 3x - 12 = 0
2x(x + 4) - 3(x + 4) = 0
(2x - 3)(x + 4) = 0
2x - 3 = 0 or x + 4 = 0, so:-
solution is 3/2, -4.
If you knew that 8*300=2400
Then you could likely figure that 8*20=160
And then just add the two together to get 2560
Answer:
x + 6
Step-by-step explanation:
consider the x- coordinates of the right angle
x- coordinate of A = - 4
x- coordinate of B = 2
then
| 2 - (- 4) | = | 2 + 4 | = | 6 | = 6
the x- coordinate has been shifted 6 units to the right , so the rule is
x + 6
