Answer:

a. plane DEA

Step-by-step explanation:

A plane can be named by naming any 3 non-collinear points in the plane, or by using the plane's name as indicated in the drawing.

Here, points in the plane are A, D, E, F, with DEF all on the same line. So A plus any two points from the line will constitute a name for the plane. Also, this plane is identified with a script M that can be used to name the plane.

M is not an answer choice, but DEA is. So, the appropriate choice is ...

plane DEA

F is a point, not a plane name. C is not on the plane, so cannot be used to name it. 'k' is a line name, not a plane name.

A dilation with a scale factor of 2 is applied to the three line segments shown. The resulting images are P′Q′¯¯¯¯¯¯¯ , A′B′¯¯¯¯

Alex

Since the scale factor of the dilation is 2, you would multiply each of the pre-image line segments' lengths by 2.

therefore,
P'Q'=4cm
A'B'=3cm
M'N'=6cm

Hope this helps you out!

How do you factor 7b^2-63b+140?

LuckyWell [14K]

You can simplify the entire equation by dividing it all by 7, resulting in 7(b^2-6b+20).

Here, you can factor as you normally would. Your X values would have to be found using the quadratic formula.
