20.000 + 4.000 + 0.300 + 0.050 + 0.007
Answer:
9 ft
Step-by-step explanation:
Here, we have a square wall with a value of 84 square feet for the area and we are told to find the approximate height of the walls
Mathematically, the area of a square is L^2
The height of the walls is just as one of its side
Thus;
L^2 = 84
L = √(84)
L = 9.165
which to the nearest foot is 9 ft
Mathematical models are helpful. Advantages include helping you see the data clearer and helping you visualize. Disadvantages are: time consuming, and if you make a mistake on the graph, its going to hit the entre thing.
Answer:
-1.9f-20
Step-by-step explanation:
-2.7f+0.8f-16-4
<em>Collect similar items</em>
-2.7f+0.8f=-1.9f
=-1.9f-16-4
<em>Subtract the numbers</em>
-16-4=-20
=-1.9f-20
Factorize both the numerator and denominator then equate to zero ...you'll get X
