Answer:
9 boards 
Step-by-step explanation:
2/3 of the porch= 6 boards 
so to figure out how much one third of the porch needs you find half of what it takes to fill in 2/3 of the porch and you get 3. 
so 3=1/3 of the porch 
then you simply do 3times 3 or 3+3+3 and you get 9
so it takes 9 boards to fill the whole porch 
 
        
             
        
        
        
8 inches
Divide 56 by 7 which equals 8 so Fred's frog jumped 8 inches.
 
        
             
        
        
        
9x^2+t+25=(ax+b)^2
9x^2+t+25=a^2*x^2+2abx+b^2 so
a^2=9 so a=3
b^2=25 so b=5 then
t=2ab using a and b from above
t=2*3*5=30
So the missing term is 30x
        
             
        
        
        
Answer:
The answer to your question is: letter C
Step-by-step explanation:
Data
Find the Parabola's equation and express the equation as an inequality.
Vertex = (0, -5)
Equation 
                                (x- h) ² = 4p(y - k)
                                x² = y + 5
                               y = x² - 5
But, we need the area upper the parabola, then
                               y ≥ x² - 5
