<span>The formula for the volume of a box is:
Volume = L*W*H
We know that the length is 10 cm.
We know that the width is twice the height, so W = 2H.
Then our volume equation is:
Volume = 10*2H*H
Volume = 20*H^2
Since H^2 is in the equation, this is a quadratic equation.</span>
C)-2/3is the answer because when your have 2/3+-2/3 will equal 0 in which justifies the additive inverse
The number of cookies packs needed if the treasurer buys 1 package of brownies bites is 5 packs
<h3>Equation</h3>
- Total attendance = 75 people
- Cookies in each pack = 12
- Brownies in each pack = 15
- Number of cookies pack = c
- Number of brownies pack = b
15b + 12c = 75
If 1 package of brownies is bought
15b + 12c = 75
15(1) + 12c = 75
15 + 12c = 75
12c = 75 - 15
12c = 60
c = 60/12
c = 5 packs
- It is a reasonable value in this context
If 9 packages of brownies are bought
15b + 12c = 75
15(9) + 12c = 75
135 + 12c = 75
12c = 75 - 135
12c = -60
c = -60/12
c = -5 packs
- The value is not reasonable in this context

Answer:
So these two equation can be related by identity 
Step-by-step explanation:
We have given equation 
And 
We know the algebraic identity 
From this identity
can be written as (x+1) (x-1)
And using same identity
can be written as 
So these two equation can be related by identity 
We know that
[scale]=1 in / 30 in
scale=measure in the drawing/measure in the actual
[measure in the actual]=measure in the drawing/scale
the measure in the drawing are
3 in x 4 in
so
for 3 in
measure in the drawing=3 in
[measure in the actual]=3/(1/30)-----> 3*30------> 90 in
for 4 in
measure in the drawing=4 in
[measure in the actual]=4/(1/30)-----> 4*30------> 120 in
the measure in the actual are
90 in x 120 in
1 ft----------> is equal to 12 in
x-------------> 90 in
x=90/12-----> 7.5 ft
1 ft----------> is equal to 12 in
x-------------> 120 in
x=120/12-----> 10 ft
the measure of a bedroom in feet are
7.5 ft x 10 ft
the area=7.5*10--------> 75 ft²
the answer is
<span>the area of the room is 75 ft</span>²
