This question is essentially asking you to find the surface area of the box.
The formula for SA on a rectangular prism is: 2(L*W+L*H+W*H)
L=Length W=Width H=Height

Lets input the information we know:
2(20*8+20*30+8*30)
Follow BEDMAS
2(160+600+240)
2(760+240)
2(1000)
2*1000
=2000

The box will need 2000 centimeters squared of material.

Hope this helps!

the temperature at noon was -27 degrees . the temperature increased by 13 degrees by 2pm . what was the temperature at 2pm
Aleks [24]
First, you would create an equation for this problem. 
-27 + 13

Now, all you would have to do is solve it. 
-27 + 13 = -14

By 2 pm the temperature was -14 degrees. 

I hope this helps!

A projectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t2 + 704t
Alex787 [66]
You need to find the x-coordinate (h) of the vertex of the parabola.

-16t^2+704t=0\\
h=-\dfrac{b}{2a}=-\dfrac{704}{2\cdot(-16)}=22


After 22 seconds.

Linear Equations. Solve the equation 5 = 3y +6 using inverse operations.
agasfer [191]

Answer:

The value of y=\frac{-1}{3}.

Step-by-step explanation:

Considering the equation

5 = 3y +6

To solve the equation 5 = 3y +6 using inverse operations,

Subtracting 6 on both sides of the equation,

5-6 = 3y +6-6

Simplifying,

-1 = 3y

Dividing both sides by 3

\frac{-1}{3} =\frac{3y}{3}

\frac{-1}{3} =y

Switching both sides

y=\frac{-1}{3}

Therefore, the value of y=\frac{-1}{3}.
