Answer:
3
Step-by-step explanation:
Note the general factorisation of a difference of 2 squares is
a² - b² = (a + b)(a + b)
Given
(- 5x - 3)(- 5x + ?)
Then ? = 3 so that the complete factors are
(- 5x - 3)(- 5x + 3)
Assuming you are asking
does -2x+y=6 and y-2x=4 have a solution
look at them
rewrite first equation by switching x and y
y-2x=6 and
y-2x=4
false since they are same values
there is no solution
these 2 lines are paralell
NO SOLUTION

Answer:
All A to D
Step-by-step explanation:
The attachment completes the question
From the attachment,
- it can be seen that QRS and TUV are of the same i.e. triangles
Also, from the attachment, the sides of each are:



And the angles are:



The above show that QRS and TUV are:
- similar
- same sides
- and they are congruent
No because the maximum amount for sin and cos is 1.if alpha is 90 and beta is 0 the answer is 7 so it's not right.
