· The volume of Olivia's rectangular lunchbox is 240 cubic inches. The lunchbox has a height of 3 inches, and its length is 2 in
miskamm [114]

The volume of a cuboid is = length × width × height.

Let the width  of Olivia's lunch box be 'x'.

Hence the length of Olivia's lunch box shall be 'x + 2'

Also the height of the box is given as 3 inches.

The volume of the box is 240 in³

Substituting in the formula we get

x(x+2)(3) =240

Dividing by 3 on both sides

x(x+2)=80

Exapnding we get

x^2+2x=80

Subtracting 80 from both sides

x^2+2x-80=0

Factoring

(x+10)(x-8)=0

We get

x= -10  or x = 8

But x cannot be negative

So x = 8

Hence the width of the box is 8 inches.

tekilochka [14]

Answer: There are 26000 miles that will both be due at the same time.

Step-by-step explanation:

Since we have given that

Number of miles required by new vintage = 400

Number of miles if these services have must been performed by the dealer = 13000

We need to find the number of miles from now that will both be due at the same time.

We would use "LCM of 400 and 13000":

As we know that LCM of 400 and 13000 is 26000.

So, there are 26000 miles that will both be due at the same time.
