Answer:
C.169
Step-by-step explanation:
Answer:
AC = 
Step-by-step explanation:
Here we have to draw the figure.
When the rectangle is folded A to C. we get a right triangle.
Here we have to use the Pythagorean theorem to find the side lenght of B.
The sides length of B is AC.
By the Pythagorean theorem, the sum of the squares of the sides is equal to the square of the hypotenuse.
Therefore,
AC^2 = AB^2 + BC^2
Taking the square roots on both sides, we get
AC = 
x=7x-21
Step-by-step explanation:
- x=7x-21
- 21=7x-x
- 21=6x
- x=21/6
- x=7/2
- x=3.5
Answer:
(x - 2)^2 + (y - 2)^2 = 3
Step-by-step explanation:
The centre point of the circle is the value for x and y
And the radius is the distance from the centre to the circumference.
i agree with martin because i added 700+490+17 and got 1,207
