The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
The area of the rectangle = length x width
= (3x² + 8x + 7)(7x²)
= 21x⁴ + 56x³ + 49x²
Thus, the expression 21x⁴ + 56x³ + 49x² represents the area of the entire rectangle.

Answer: b) 15.7
<u>Step-by-step explanation:</u>
Look at the z-table (below) to find 0.2500
Notice that the value is not on the table but is between 0.2486 and 0.2517 which are located on the z-table at 0.67 and 0.68
The given value is closer to 0.2486 so use 0.67 as the z-score.
Now, let's find the x-value using the formula:
