Answer:
B is the answer for this question. :)
Step-by-step explanation:
Answer:
x^2 + 8x + 16
Step-by-step explanation:
(x + 4) (x+ 4) multiply x by x and x by 4.
x^2 + 4x
Then multiply 4 by x and 4 by 4.
4x + 16
Then combine like terms.
x^2 + 4x + 4x +16
x^2 + 8x + 16
Step-by-step explanation:
So the Ap will be x,x+10,x+20,x+30
Sum of the angles of a quadrilateral is 360
x+x+10+x+20+x+30=360
4x+60=360
4x=300
x=75
So the angles are 75,85,95,105
Answer: Your answer is A. y= 2.5sin x
Given data is that circles are identical. According to this diameters are identical too.
Diameter of the first circle is 4x and for the second 2x+3.
We can make equality 4x = 2x+3 => 2x=3 => x=3/2
Circumference of each circle is C= 2r pi = 2*(3/2) pi = 3 pi
The correct is fifth answer.
Good luck!
