1) this is total area of two triangle
area of a triangle=1/2*b*h
A=1/2*9*4
A=18 inches^2
multiply by 2 because there are two triangle with same measure
2A=2*18=36 inches^2
3) this is a area of rectangle and a triangle and then subtract
A2=9.3x7.8= 72.54
area of triangle A1=1/2*7.8 *3.3=12.87
A2-A1=59.69 mm^2
5) now u ca do it
1/2 * 5 = 2.5.
You would need 2.5 boxes to build 5 birdhouses.
The correct answer is D. 13 + 8i
Answer:

And solving we have:


And we can write the expression like this:

The vertex for this case would be:

And the minimum for the function would be 3 and there is no maximum value for the function
Step-by-step explanation:
For this case we have the following equation given:

We can complete the square like this:

And solving we have:


And we can write the expression like this:

The vertex for this case would be:

And the minimum for the function would be 3 and there is no maximum value for the function
Answer:
-20
Step-by-step explanation:
First, you divide both sides by -2/5, which would get you c = 8 * -5/2 (Because when you divide, you multiply by the reciprocal). 8 * -5/2 is equal to -20. The answer is -20.
