Answer:
D
Step-by-step explanation:
The degree of a polynomial is determined by the largest exponent of a term within the polynomial.
Given
7x³ + 4x - 5 + 8
The term with the largest exponent is 8 with exponent 5
Thus the polynomial is of degree 5 → D
The area of the rectangle is units.
Step-by-step explanation:
Step 1:
The area of a rectangle is obtained by multiplying the length with the width of the rectangle.
Considering this a whole rectangle, the length of the rectangle is 5 units and the width is the sum of ,
, and -6.
So the length of the rectangle = 5 units and
the width of the rectangle units.
The area of a rectangle = (length)(width).
Step 2:
By substituting the known values, we get
The area of the rectangle
So the area of the rectangle is units.
