Answer:
Here, l is the length of the rectangle and w is the width of the rectangle
To Compare the values, you must calculate each given situation.
Area of a rectangle is equal to length times width.
i.e, 
(A)
if l = 8 units and w= 6 units,
then;
= 
(B)
if l =7 units and w = 7 units
= 
Therefore, the Part B would yield a larger area.
If l -7 units and w = 7 units , the area of larger floor is 49 square units.
Answer:
t = 1
Step-by-step explanation:
1) Subtract 4 from both sides so you get -2t = -2
2) Divide both sides by 2 so you get t = 1
Using inequality for the give interval which states that :
A function lies in an open interval from -2 to 6.
Hence,we can rewrite it as :
-2 < x < 6
Answer:
4 ft
7.2 ft
20 ft
Step-by-step explanation:
When the balloon is shot, x = 0.
y = -0.05(0)² + 0.8(0) + 4
y = 4
The balloon reaches the highest point at the vertex of the parabola.
x = -b / 2a
x = -0.8 / (2 × -0.05)
x = 8
y = -0.05(8)² + 0.8(8) + 4
y = 7.2
When the balloon lands, y = 0.
0 = -0.05x² + 0.8x + 4
0 = x² − 16x − 80
0 = (x + 4) (x − 20)
x = -4 or 20
Since x > 0, x = 20.
Infinitely many, because if you simplified the right side, it would equal the left side.
