We have building B was built two years before building C.
The age of C is represented by x
Age of Building B:
b = x + 2
Building D was built two years before building B
Age of Building d= x+4
The product of the building B’s age and building D’s age is at least 195.
b×d ≥ 195
(x+ 2)(x+4) ≥ 195
After solving we get:
x²+ 6x +8 ≥ 195
Thus, the inequality x²+6x +8 ≥ 195 represents the provided situation option (D) x²+ 6x +8 ≥ 195 is correct.

Answer:
The result in standard form is:
Step-by-step explanation:
Given the polynomials
- -5t+ 4t² – t
- 8t² + t
subtracting 8t² + t from -5t+ 4t² – t.
Remove parenthese: (-a) = -a
i.e. - (8t² + t) = 8t² - t
so the expression becomes
grouping the like terms
Add similar elements: 4t² - 8t² = -4t²
Add similar elements: -5t - t - t = -7t
Therefore, the result in standard form is:
