height= 3

length= 5

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

3 x 5 x 4 = 60

We need 60 blocks

height= 4

length= 6

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

4 x 6 x 4 = 96

We need 96 blocks

height= 2

length= 3

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

2 x 3 x 4 = 24

We need 24 blocks

height= 4

length= 8

width= 6

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

4 x 8 x 6 = 192

We need 192 blocks

height= 2

length= 6

width= 4

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

2 x 6 x 4 = 48

We need 48 blocks

height= 1

length= 5

width= 3

The number of cubes would be the result of the multiplication of the side measures. Doing so, we have:

1 x 5 x 3 = 15

We need 15 blocks

Simplify the expression (x^3- 5x^2 + 7x - 12) ÷ (x – 4) using long division

Kisachek [45]

Answer:

${x}^{2} - x + 3$

Step-by-step explanation:

Instead, since the divisor is in the form of $x - c$ , use what is called Synthetic Division. Remember, in this formula, $-c$ gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:

4| 1 −5 7 −12

↓ 4 −4 12

_______________

1 −1 3 0 → ${x}^{2} - x + 3$

You start by placing the $c$ in the top left corner, then list all the coefficients of your dividend [x³ - 5x² + 7x - 12]. You bring down the original term closest to $c$ then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient can be an ${x}^{2}$ , the −1 [ $x$ ] follows right behind it, and bringing up the rear, comes the 3, giving you the quotient of ${x}^{2} - x + 3$ .
