What are u asking me too do factor simplify??
Answer:
Step-by-step explanation:
how we supposed to do it , when we cant control it
We know that
If the scalar product of two vectors<span> is zero, both vectors are </span><span>orthogonal
</span><span>A. (-2,5)
</span>(-2,5)*(1,5)-------> -2*1+5*5=23-----------> <span>are not orthogonal
</span><span>B. (10,-2)
</span>(10,-2)*(1,5)-------> 10*1-2*5=0-----------> are orthogonal
<span>C. (-1,-5)
</span>(-1,-5)*(1,5)-------> -1*1-5*5=-26-----------> are not orthogonal
<span>D. (-5,1)
</span>(-5,1)*(1,5)-------> -5*1+1*5=0-----------> are orthogonal
the answer is
B. (10,-2) and D. (-5,1) are orthogonal to (1,5)

Answer:
Tom started out with 57 games but sold 37 of them.
=> Now, Tom has: 57 - 37 =20 games
He put the rest in boxes with 5 games in each.
=> The number of boxes: 20/5 = 4 box
Hope this helps!
