Answer:
33.22 square inches
Step-by-step explanation:
Diameter to Radius:  
 
Area of Circle:  
 
 We are given the diameter of a pancake as 4.6 inches, so the radius is 2.3 inches. Next, we have to apply the area of circle formula with pi as 3.14 and the radius as 2.3
Next, since there's two pancakes, we double 16.6106.
Lastly, we round to the nearest hundredth.
- 33.2212 ≈ 33.22 square inches 
Therefore, the answer is 33.22 square inches.

Answer: 2
Step-by-step explanation:
x-intercepts are points on a graph that lie directly on the x-axis and have 0 as their y-coordinate value. To find the x-intercepts, we just have to replace the y in the equation with 0. 
y = (2x+5)(x-9) 
0 = (2x+5)(x-9) 
<em>Apply zero product rule. </em>
2x+5 = 0  OR  x-9 = 0 
x = - OR x = 9
  OR x = 9 
Thus, the two coordinates of the x-intercepts are: (- , 0) and (9, 0)
, 0) and (9, 0) 
 
        
             
        
        
        
Answer:
D. -3.0 < x < 7.5
Step-by-step explanation:
Given the side lengths of a triangle: 6.5 units, 3.5 units, and 2.5 + x units
For the triangle to exist:
- A side length cannot be negative
- A side length cannot be zero
Therefore, the third side length
x+2.5>0
x>-2.5
x must be greater than -2.5 and less than or equal to 6.5 units.
The correct option is D which satisfies this condition.
D. -3.0 < x < 7.5
