Considering the following statements, what is X - Z?
X - Y: If the sum of the interior angles of a shape is 180°, then it's a triangle.
Y - Z: If a shape is a triangle, then it has three sides.
OA) X – Z: If the sum of the interior angles of a shape isn't 180°, then it doesn't
have three sides.
B) X - Z: If the sum of the interior angles of a shape is 180°, then it has three
sides.
C) X - Z: If a shape has three sides, then it's a triangle.
OD X – Z: If a shape has three sides, then the sum of the interior angles of the
shape is 180°

r and t.

both are 64 degrees.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
