Answer:
3
Step-by-step explanation:
((7x-4)^2) - (7x-4)(7x-4) + 3
(7x-4)(7x-4) is 7x-4^2
So its (7x-4)^2 - (7x-4)^2 + 3
(7x-4)^2 cancel out.
Answer is 3
⟨0,1⟩ could be taken to begin at the origin and end at (0,1). <span> ⟨0,1⟩ has the length/magnitude of 1 and direction j. So the desired unit vector is simply j.</span>
Answer:
its the same thing as 3 x3 or 3+3 it always come´s back as 9 or 6 Becasue of its rotation
Step-by-step explanation:
In equations you must do the same to both sides so that the equation stays equal. also, it's easier to solve if you get the unknowns on one side.
so first you distribute
-7(x-4) means (-7 times x) + (-7 times -4) so -7x+28
-7x+28+8x=12+14
add like terms
x+28=26
subtract 28 from both sides
x=-2
