2 answers:
ANSWER
The correct answer is A.
EXPLANATION
If you know the diagonals of a kite you can easily find the area.
The area of a kite is half the product of the diagonals.
From the graph, the from -5 to 4.
Using the number line approach. The longer diagonal is
Similarly the shorter diagonal is from -4 to 4
The area of the kite is:
This implies that
The first choice is correct.

Answer:
Step-by-step explanation:
We wil define:
1) "x" as number of cans inside the truck.
2) "y" as number of bottles inside the truck.
We now that the amount of both cans and bottles inside the truck is "980". This quantity is equal to the sum of cans and bottles, so now we can write:
We will call this expression equation n° 1.
On the other hand, we know that the total weight is a sum of the weight of the cans and the weight of the bottles. The total weight of the cans, for example, is the result of multiplying the numbers of cans in the truck with the weight of each can, like here: (
So now we can write:
We well call this expression equation n° 2.
From equation n°1 we obtain "y", like this:
And we replace it in equation n°2:
Now we have the expression of the total weight considering the amount of cans in the truck.
*** IMPORTANT: there is a character similar to an "A" that i can't erase, maybe is a mistake from brainly. Do not consider it as part of the solution.
