You add another row and the row has to be one taller than the row before it
Answer:
Step-by-step explanation:
If the ratio of the sides is 13:14:15, we can say that the length of each side is 13x, 14x and 15x.
Then, if the perimeter is 84 m, we have:
The length of each side is:
Now, to find the area of the field, we can use the following formula:
Where a, b and c are the sides and p is the semi perimeter:
So we have that:
Answer:
AAA
Step-by-step explanation:
AAA is not a congruence theorem or postulate.
I believe she would need to stain 548 inches of the surface.
Excluding the top and bottom, you are left with two panels that are 10 by 7.4, and two panels that are10 by 20, so
10•7.4= 74•2 =148
10•20= 200•2 =400
148 + 400= 548
Please correct me if I am wrong, have a good day!
Let F(x) = x^2 + 2x -8
Adding 1 and - 1 at equation
F(x) = x^2 + 2x + 1 - 1 -8
Rewrinting the first 1 = 1^2
F(x) = x^2 + 2x + 1^2 - 1 - 8
Now look:
x^2 + 2x + 1^2 = ( x + 1)^2
Then,
F(x) = (x + 1)^2 -1 -8
F(x) = (x + 1)^2 -9
This is the answer !
If us to want.
(x + 1)^2 -9 = ( x+1)^2 - 3^2
= ( x+ 1 -3).(x +1 +3)
= ( x - 2).(x +4)
