18 = 2·3·3

So possibles prisms are:

2×3×3

1×2×9

1×6×3

1×1×18

Therefore Quentin can make 4 different rectangular prism with 18 unit cubes.

Answer:

Quentin could built 3 different rectangular prism.

Step-by-step explanation:

Quentin could built by arranging the unit cubes in rows and columns.  Let us say  R units cubes are in a row  and  C unit cubes in a column.

R × C = 18 = 1 × 2 × 3 × 6 × 9 × 18

1.  R = 18    C = 1        This  prism is same as  if R = 1 and C = 18

2.  R = 9   C = 2              same if  R = 2,  C = 9

3.  R = 3    C = 6

So answer is 3.

Answer:

10x^2-11x-6

Step-by-step explanation:

To expand, we use the FOIL method. You do this by multiplying each number inside the parenthesis by the other numbers in the other set of the parenthesis. For example, on this problem, you would multiply 5x by 2x, and then 5x by -3.

Step by step, you would:

5x * 2x = 10x^2

5x * -3 = -15x

2 * 2x = 4x

2 * -3 = -6

In an equation, it would expand to 10x^2-15x+4x-6

To simplify, you add like terms (constants and those with the same variable). In this case, you would add together all the terms ending in x.

-15x+4x=-11x

Now, you have added like terms together, so your simplified answer is 10x^2-11x-6.

What is 2 gallons minus 5 quarts
MariettaO [177]
There are 4 quarts in a gallon.
In two gallons would be 8 quarts.

2 gallons - 5 quarts = 8 quarts - 5 quarts = 3 quarts.

Note: 3 quarts is 3/4 or .75 of a gallon.

You recently purchased a new snowboard for the upcoming winter. The board, with bindings, came out to be $315.32. You were told
gizmo_the_mogwai [7]
First the original price is reduced by 15%
assume the original price is x
100%-15%=85%..u r left with 85% of the price
thus,85/100 multiply x
the reduced price is reduced again by 5%
so,95/100 ×(85/100 x)=$315.32
find x
323/400 x =$315.32
×=$390.49
