Step-by-step explanation:
You can let me know, but i dont think -3x² is supposed to be squared in this question because then it would make it unsolvable.
5x-15
can be simplified to 5(x-3)
x²-3x
can be simplified to x(x-3)
Then u rewrite it (5 + x)(x - 3)
Answer:
(x + 3) (x - 1
Step-by-step explanation:
<em>here's</em><em> your</em><em> solution</em>
<em> </em><em> </em><em>=</em><em>></em><em> </em>x^2 + 2x - 3
=>. By using middle term split
=> x^2 + 3x - x - 3
=> taking common
=> x( x + 3) - 1(x + 3)
=> (x + 3) (x - 1)
Hope it helps

Since

for

, we have

, so we take the positive root. Now,

- - -


In the first quadrant, cosine is positive, so

and in turn,


- - -
In the previous problem, we had

, so we must have

, which means
If they are congrunt, and it seems like the shape was rotated, so the answer is D
Answer:
I think it would be a
Step-by-step explanation:
I think it would be a because when you divide by a negative number the sign flips
