The area of Jordan’s yard can be modeled by the expression 3x2 – 2x + 1. Jordan purchases additional land from his neighbors. The area of this land can be modeled by the expression 4x2 + 3x + 7. Which expression represents the new area of Jordan’s yard?

A.
x2 + 5x + 6

B.
x2 + x + 8

C.
7x2 + x + 8

D.
7x2 + 5x + 6

Answer 1

7x^2 + x + 8

Explanation:

here's your solution

=> The model of Jordan yard = 3x^2 - 2x + 1

=> The model of new yard = 4x^2 + 3x+ 7

=> now, for total area we need to add both

=> 4x^2 + 3x^2 + 3x - 2x + 7 + 1

=>7x^2 + x + 8

hope it helps
