A unit rate is just how much it costs per ONE unit of whatever your measuring. Lets say you had a rate of $4.00/8lbs. The unit rate would be $0.50/ ONE lb.

Use function notation to represent how much the volume of the box (in cubic inches) changes by if the cutout length increases fr
MakcuM [25]

Answer:

Increases 64 times

Step-by-step explanation:

The volume of the box can be calculated using formula

V=l\cdot w\cdot h,

where

V = volume,

l = length,

w = width,

h = height

If the length was 0.3 inches, then the volume was

V_1=0.3\cdot w\cdot h=0.3wh

When the length became 1.2 inches, then all dimensions became 1.2 :0.3 =4 times greater, then the volume was

V_2=1.2\cdot (4w)\cdot (4h)=19.2wh

The volume increases

\dfrac{V_2}{V_1}=\dfrac{1.92wh}{0.3wh}=64 times

Anarel [89]

Answer:

- 7

Step-by-step explanation:

Solve for x

3x + 3 = - 9 ( subtract 3 from both sides )

3x = - 12 ( divide both sides by 3 )

x = - 4

Hence

3x + 5 = (3 × - 4) + 5 = - 12 + 5 = - 7
