The solution to the answer is as follows:
<span>x - y = 1...[1],
2x + y = 19...[2], {[1]+[2]}---> 3x = 30,
ie., x = 10. C is correct answer.

I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:306
Step-by-step explanation:
since the width of the bottom square is 10, you split it between the triangles on top. You have to do this because 7 is not the whole width of the two triangles. So then the width of the triangles would be 12, 12 times 9 is 108, you'd have 216 total for both triangles and then the area of the square is 90, 90 plus 216 is 306.
Answer:
There are no graphs, but the graph should look lyke this:
An open circle on the point "10"
And from the 10, the arrow should be going left, towards the negatives, or smaller numbers than the ten
The number 20 is not a prime number.
