Answer:
Step-by-step explanation:
3x^2 + 7x + 9x^2 - 3x + 2
3x^2 + 9x^2 + 7x - 3x + 2
12x^2 + 7x - 3x + 2
Answer: 12x^2 + 4x + 2
This should be correct unless i'm dumb...
The answer should be 5 over 4
Step-by-step explanation:
We can call the original value x. In 2012, the painting's value was 1.05 x. In the beginning of 2013, the value was (1.05 x) * 0.98, and that increased to (1.05x) * 0.98 * 1.40 at the end of 2013. When we simplify, we get 1.4406 x as a value, and we know that this is equal to $52,640. We can write 1.4406x = 52640, and when we solve for x, we get x ≈ $36415.38. Hope this helps!
Answer:
51
Step-by-step explanation:
sum of exterior angles = 360
64 + 60 + 69 + 42 + x + x +23 = 360
2x + 258 = 360
2x = 360 - 258
2x = 102
x = 51
(8.4, 8.4) or 
Explanation:
Given points are A(2, 6) and B(18, 12).
Let P(x, y) partitions the line segment in the ratio 2 : 3.
That is AP : PB = 2 : 3.
A(2, 6) can be taken as 
B(18, 12) can be taken as 
AP : PB can be taken as m : n = 2 : 3.
The coordinate of point P(x, y) divides line segment joining 
and 
in ratio m : n is
Here, 
and m = 2, n = 3.
Substitute these in the above formula, we get
= (8.4, 8.4)
Hence, the point partitions the line segment is (8.4, 8.4) or .
