Answer:
w = -7, -6
Step-by-step explanation:
Solve the equation by factoring:
(w+7)(w+6) = 0
Set each parenthesis equal to zero, and solve for w:
w = -7, -6
Hope this helps!

Answer: y=9
Step-by-step explanation:
Simplifying
7y = 3y + 36
Reorder the terms:
7y = 36 + 3y
Solving
7y = 36 + 3y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3y' to each side of the equation.
7y + -3y = 36 + 3y + -3y
Combine like terms: 7y + -3y = 4y
4y = 36 + 3y + -3y
Combine like terms: 3y + -3y = 0
4y = 36 + 0
4y = 36
Divide each side by '4'.
y = 9
Simplifying
y = 9

Answer:
MN = 7 cm
Step-by-step explanation:
Well the volume we can separate into pieces
first the ABCDEFGH (? you know this cuboid)
which has a volume of
if you ask where does the 4 come from
it comes from LP = KB = YC and JY + YC =JC
so
this is because JY = MX
the other volume is of BCNPKLXY (hope you understand which one)
and the volume is
and the last one is KYXLMJ (the top "triangle")
the volume is
so now add them up
and has to equal 444
and finally we know that MN = MX + XN = 3+4 = 7
so here is our answer MN = 7 cm
a couple of notes
3. the units don't matter due to the fact that everything is in cm
4. see the picture below to get a better idea of which prism I am talking of
5. tell me if you have questions :D
Answer: 3 boxes
Step-by-step explanation:
if each friend is going to get 4 cookies, you should multiply 7x4, which gets you 28. The divide 28 among the 12. Which will mean that one box can help 3 friends, so 2 boxes helps 6 friends, but since Alvin has 7 you need to get an extra box, so 3
