8 ) 712
8 goes into 71 8 times; the product of 8 and 8 is 64.
Subtracting this 64 from 71, we get 7, to which we append 2: 8 ) 72.
8 divides evenly into 72: 9.
Thus, the desired quotient is 89.
For this case what you should do is:
1) Multiplication of terms within parentheses correctly.
2) Rewrite the expression respecting power properties.
3) Add or subtract terms of equal power.

Answer:
x ^ 3 + 3x ^ 2 -16x - 48 = 0
Answer:
The approximate area of the cross section passing through the diagonals of opposite faces of this cube is:
- C. <u>35 square centimeters</u>.
Step-by-step explanation:
When you think in the cross section passing through the diagonals of opposite faces of the cube given, you can see that it's a rectangle with long = 7 centimeters and wide = 5 centimeters ( the measure of an edge of the cube), having this, you can calculate the area:
- Area of a rectangle = long * wide
- Area of a rectangle = 7 cm * 5 cm
- <u>Area of a rectangle = 35 cm^2 or 35 square centimeters</u>
