Answer:
D. –X+XY–7y
Step-by-step explanation:
We just have to combine (add) the similar terms... so all terms that have an x in them for example.
–3x + 2xy + 4y – xy + 2x – 11y
Let's first re-write it placing similar terms next to each other
(-3x + 2x) + (2xy - xy) + (4y - 11y)
Then we sum them up, for each similar terms
1x + 1xy -7y
so, x + xy -7y

105-30-45-3028+10000000000000038492= 1.000000000000003e19
Step-by-step explanation:
I did the math
have a good day!!
The correct answer is 64 square units.
The area of the complete shape would be 100 square inches.
10 x 10 = 100
However, we have to remove the 4 corners. Each of the corners is 9 square inches. 3 x 3 = 9
100 - 4(9) = 64
Triangle inequality rule states that the sum of eachpair of sides must be greater than the third sides.
240 + 123 > 207 true
240 + 207 > 123 true
123 + 207 > 240 true
A = √(s(s-a)(s-b)(s-c))
s is the semi-perimeter (a + b + c)/2
s = (240 + 123 + 207)/2
s = 285
A = √(285*(285-249)(285-123)(285-207))
A = 12,730 units^2
