The solution is (8,-12) if it was solved by elimination
The inequality x²+6x +8 ≥ 195 represents the provided situation option (D) x²+ 6x +8 ≥ 195 is correct.
<h3>What is inequality?</h3>
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
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.

x=9 units, y=12 units, u=24 units and v=32 units
Step-by-step explanation:
The question is on similarity.
The ratio of corresponding sides should be equal for the triangles to be similar.
Finding x
20/5=(3+x )/3
apply cross product
60=15+5x
60-15=5x
45=5x
45/5=x
9=x
Finding y
20/5=(4+y)/4
Apply cross product
80=20+5y
80-20=5y
60=5y
60/5 =y
12=y
Finding u after replacing values of x and y
60/20 = (12+u)/12
perform cross product
720=240 +20 u
720-240 =20u
480 =20 u
480/20 =u
24 =u
Finding v after replacing values of x and y
60/20 = (16+v)/16
perform cross product
960=320+20v
960-320 = 20v
640=20v
640/20 =v
32= v

Answer:
The result in standard form is:

Step-by-step explanation:
Given the polynomials
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:
