Answer:
468 sq. ft.
Step-by-step explanation:
A = 1/2 (a + b) (h)
= 1/2 (52) (18)
= 468 sq. ft.
The number 4,770,000 in appropriate scientific notation would be 4.770000x10^16
Well I got j for this. I picked a prim number for ex 5 and tries it with each problem.
The first picture shows solution for a. For b). X=9,2
The correct answer is is D) If the group sells 15 prints they will loose $85.
To figure out which statement is true, we have to evaluate the function ,
for all the values given in options (A)-(D). A negative output represents a loss and a positive output will represent a profit.
In A 
so 
. In this case we gather that if they sell 12 prints, they will make a loss of $136. This tells us that option A is wrong.
In B, 
so 
. In this case we gather that if they sell 28 prints, they make a profit of $136. This tells us that option B is wrong.
In C, 
so 
. In this case we gather that if they sell 35 prints, they make a profit of $225. This tells us that option C is wrong.
Lastly, 
so 
. In this case we gather that if they sell 28 prints, they make a loss of 85 dollars. From this we gather that D is the correct option.
