We know that
<span>(16x6 − 12x4 + 4x2) / 4x2
is equal to
[16x6/4x2]+[-12x4/4x2]+[4x2/4x2]
=[4x4]+[-3x2]+[1]
=4x4-3x2+1
the answer is
</span>4x4-3x2+1<span>
</span>
Answer:
I think you should try the method of substitution???
You would have to do 24.85 x 4 because the 24.85 is per hour and if someone is going for 4 hours, this is what we would have to work out. So it would equal: 99.40 miles per hour. :)
it would be 13
Step-by-step explanation:
Answer: x-y=2
Step-by-step explanation:
y+5=x+3; move variable (x) to the left-hand side and change the sign.
y-x+5=3; move the constant to the right-hand side & change the sign
y+x=3-5; reorder the terms
-x+y=3-5; calculate
-x+y=-2; change the signs on both sides
x-y=2 is your answer! hope this helps!
