Answer:
Step-by-step explanation:
First, use the distributive property 
Thus,
Then given expression will take look
This expression consists of three terms, one term with m and two terms without m. Combine terms without m:
Therefore, an equivalent expression is
1,4,6
4 because 2:1 is equal to 4:2. 6 because 3:1 is equal to 6:2
Answer:
x(x^2 + 6)
Step-by-step explanation:
We are to simplify -3x(x-4)-2x(x+3). Begin by performing the indicated multiplication. We get -3x^2 + 12x - 2x^2 - 6x.
Combining like terms, we get -5x^2 + 6x, which is equivalent to
x(x^2 + 6)
You do the difference divided by the starting number.
518 - 422 = 96 (the difference)
422 is the starting number.
96/422 = 0.227488 (rounded up)
if 1 is 100% then 1+0.2227488 would be the increase.
1 + 0.227488 = 1.227488
1.227 = 122.7%
Let
x----------> the number of students
y---------> the time in minutes
we know that
<span>If the time varies inversely with the number of students
</span>so
y=k/x
for x=3
y=16 min
16=k/3---------> k=48
y=48/x
for x=2
y=48/2-------> y=24 minutes
the answer is
24 minutes
