Step-by-step explanation:

Ana began her work effectively by multiplying factors to arrive at:\

$(x+4)(x+2)(2x+1)(x-2)=0$

She accurately multiplied $(x+2)(x-2)$ through the difference of two squares obtaining: $x^2-4$

Unfortunately, she erred in her multiplication for $(x+4)(2x+1)$ and incorrectly arrived at $x^2+9x+4$ , missing the coefficient of 2. $2x^2+9x+4$ Thus, the correct second step should be:

$(x^2-4)(2x^2+9x+4)$ The subsequent step will then be:

$2x^4+9x^3+4x^2-8x^4-36x-16=0$ This reduces to

Which statements are true regarding the diagram? Check all that apply.

Zina [9154]

Answer:

2.CE lies on line m.

4.Ray AD is identical to ray AC.

6.Angle ECB is formed by CE and CB.

Step-by-step explanation:

A diagram has been provided.

Our task is to identify the valid statements regarding the diagram.

1.CB is found on line n.

CB does not align with line n since points C and B do not lie on that line.

Thus, this statement is false.

2.CE is situated on line m.

CE is indeed positioned on line m because points C and E are both on this line.

This statement is accurate.

3.Ray BC is equivalent to ray CB.

A ray begins at a single point and continues indefinitely without a terminal point.

Ray CB starts at point C and stretches out from point B.

However, ray BC does not exist.

This statement is therefore false.

4.Ray AD is equivalent to ray AC.

Both AD and AC are rays.

They are equivalent since both originate from point A and extend in the same direction.

5.Angle EAD is formed from AE and DA.

This is false because angle EAD is created by ray AE and ray AD, not by ray DA.

6.Angle ECB is generated by CE and CB.

This is true as angle ECB is made by ray EC and ray BC.

Answer:

This is how the money should be divided:

Each of my two younger siblings receives P3,000.

I will take P4,000.

The reasoning for this allocation stems from the principle that the eldest and youngest siblings should not receive equal portions when dividing assets.

Step-by-step explanation:

This division approach is the only sensible method to distribute P10,000 among myself and my younger siblings while ensuring no fractions are involved, maintaining whole peso amounts. Any other method would result in leftover change.
