Answer:
ok i will teach all just chat me
Step-by-step explanation:
ok
4x² - 12x = 7
- 7 - 7
4x² - 12x - 7 = 0
4x² + 2x - 14x - 7 = 0
2x(2x) + 2x(1) - 7(2x) - 7(1) = 0
2x(2x + 1) - 7(2x + 1) = 0
(2x - 7)(2x + 1) = 0
2x - 7 = 0 or 2x + 1 = 0
+ 7 + 7 - 1 - 1
2x = 7 2x = -1
2 2 2 2
x = 3¹/₂ or x = ⁻¹/₂
Answer:
I think it's 3 units so you got that right
2 and 1/2 - 1 and 1/2
since both equations have 1/2, 1/2 - 1/2 automatically is 0
then youll need to subtract 1 from 2 which is 1
Answer- 1
Answer:
164.7
Step-by-step explanation:
So if v= 7 and w=8, then the problem would become - 11.3 x 7 plus 10.7 x 8.
simplified, this would be 79.1 + 85.6, so add that and you should get 164.7
