$9w^5 + 24w^4 + 16w^3$

Factor out w³.

$w^3(9w^2+24w+16)$

Find two numbers that multiply to equal 144 (9*16) and add to equal 24.
This would be 12 and 12.

$w^3(9w^2+12w+12w$

Factor.

$w^3(3w(3w+4)+4(3w+4))$ +16)[/tex]

Simplify.

$w^3(3w+4)(3w+4) = w^3(3w+4)^2$

someone pls help!!! Complete the proofs using the most appropriate method. Some may require CPCTC. I will give brainly

Softa [21]

Answer:

I can't write out the whole proof here.

it bisects, so we know BCA is congruent to DCA

abc being congruent to adc is given

AC = AC because it is a singular side

AAS

then the lines are congruent by CPCTC

A car is advertised as $288/month for 72 months. What is the cost of the car?

viktelen [127]

Answer:

$20,736

Step-by-step explanation:

When these kind of advertisements are displayed,, it means the EMI cost per month shall be $288.

Since it provides the time period, that is 72 months,

Total cost of car in this case shall be $288 $\times$ 72 months = $20,736

Also, these include an interest factor, but overall it is = $20,736 only,

If one down payment for full price of the car is made the cost shall reduce by the interest amount, but since no interest rate is provided it shall be ignored.
