Which steps would prove the circles similar? Translate the circles so they share a common center
point, and dilate circle Y by a scale factor of 4.
O Translate the circles so the center of one circle rests
on the edge of the other circle, and dilate circle Y by
a scale factor of 4.
O Translate the circles so they share a common center
point, and dilate circle Y by a scale factor of 3.
O Translate the circles so the center of one circle rests
on the edge of the other circle, and dilate circle Y by
a scale factor of 3.

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

the answer is 8.64
