Answer:
No
Step-by-step explanation:
The equation of a circle with center (a,b) and radius r is given as:

If a given point (x,y) does not lie on this circle, it will not satisfy its equation.
This means the distance from the point to the center is not equal to the radius.
It is either less or greater than the radius.
Hence you cannot write the equation of the circle.
3u + 4u + 2u = 9u
9u = 90
1u = 90/9 = 10
since black is 2u ( from the ratio given)
2u = 10 x 2 = 20
Answer : 20cm of the pole is painted black.

Answer:
the right answer is -3
Step-by-step explanation:
When we analyze the sequence it is observed that all numbers are multiplied by the value of -3.
using the formula
q = 
F=5 dollar bills
t=twent dollar bills
38 total bills
f+t=38
400 in bills
400=5f+20t
we have
f+t=38
5f+20t=400
multipy first equation by -5 and add to second equation
-5f-5t=-190
5f+20t=400 +
0f+15t=210
15t=210
divide both sides by 15
t=14
subsitute
t+f=38
15+f=38
f=23
23 five dolar bills
15 twenty dollar bills
Answer:
Step-by-step explanation:
(2x+1)^2+(2x^2+2x)^2=
(2x+1)^2=4x^2+4x+1
(2x^2+2x)^2=4x^4+8x^3+4x^2
4x^2+4x+1+4x^4+8x^3+4x^2=4x^4+8x^3+8x^2+4x+1
(2x^2+2x+1)^2=4x^4+8x^3+8x^2+4x+1
4x^4+8x^3+8x^2+4x+1=4x^4+8x^3+8x^2+4x+1
