Answer:

<BAE is congruent to <DAC (first choice)

Step-by-step explanation:

Triangle ACD has three angles: <DAC, <ACD, <ADC

Triangle ABE has three angles: <BAE, <AEB, <ABE

Angles ACD, ADC, AEB and ABE are all different angles. Look them up in the figure, and you'll see they are 4 different angles.

Angles BAE and DAC are the same angle.

Answer: <BAE is congruent to <DAC (first choice)

What is the quotient (125-8x^3) divided by (25+10x+4x^2)

Alenkinab [10]

Answer:

-2x + 5

Step-by-step explanation:

When you set this problem up:

$\frac{125-8x^{3} }{25+10x+4x^{2} }$

It's easy to see that you can't really divide them due to their differing variables. So, we need to factor the numerator to give us equivalent variables:

$factor: -8x^{3} +125 = -(2x-5)(4x^2 +10x+25)$

WAIT! Look at the longer factor:

$4x^2+10x+25$

It is equivalent to our denominator! Now, that has made the job incredibly easier. Simply cancel out the like terms in the problem and we have our answer:

(-2x + 5)
