DerKrebs [107]3 years ago

Answer:

3(2x+2) = 6x + 6

Step-by-step explanation:

Those are algebra tiles, so it is saying (if you read across the top) 2x +2 then if you read down you have 3 units, so the dot means 2x + 2 multiplied by 3

If you write it in algebraic terms it is 3(2x+2) so the answer when you distribute is 3 (2x) + 3(2) so 6x + 6, and if you count the number of red rectangles you have 6 of them, hence the 6x, and if you cound the units in gray you have 6 of them, hence the 6.

Algebra tiles are used to demonstrate algebra concepts

A rectangular tank measures 20cm x 30cm x 40cm. You want to fill it by using a cubic container that is 20cm on each side to carr
umka2103 [35]

Answer:

4 trips

Step-by-step explanation:

Given that:

Dimension of rectangular tank :

(20cm * 30cm * 40cm)

Dimension of cubic container used to fill tank = 20cm per side

Volume of tank = (20 * 30 * 40) = 24400 cm³

Volume of cubic container = (20 * 20 * 20) = 8000 cm³

Number of trips it would take :

Volume of tank / volume of container

24400 cm³ / 8000 cm³

= 3.05

Hence, it will take 4 trips
