Answer: 4x+10y
you can't simplify 4x+10y
I don't see the question . What is the question
Answer: x² + y² = 25
Step-by-step explanation: As we have x²+y²=25 (A) as options,
x-y=1 (B)
x+y=25 (C)
x²+y²=5 (D)
We can rule out B and C as they are not circles. Circles must be
(x - xc)² + (y - yc)² = r². They must have index 2.
We have then A or D.
As the circle must pass through (3,4), we can substitute as x=3 and y=4
(A) 3² + 4² = 9 + 16 = 25 ok
(D) 3² + 4² = 9 + 16 = 25 ≠ 5
So, it is A, x² + y² = 25
51.
2+3x = 62
3x = 60
x = 20
52.
6x+2 + 40 = 90
6x = 48
x = 8
53.
3x+18 + 93 = 180
3x = 69
x = 23
54.
x-24 + 29 + 296 = 360
x = 59
The first two are the horizontal the second one is vertical.
