Factor. Explain. 24x³y²-4x²y+84x^4

Elan Coil [88]

Answer:

$\boxed{\bold{4x^2\left(6xy^2-y+21x^2\right)}}$

Step By Step Explanation:

Apply Exponent Rule $\bold{\:a^{b+c}=a^ba^c}$

$\bold{x^4=x^2x^2,\:x^3y^2=x^2x}$

$\bold{24x^2x-4x^2y+84x^2x^2}$

Rewrite 84: $\bold{21\cdot \:4}$

Rewrite 24: $\bold{6\cdot \:4}$

$\bold{6\cdot \:4x^2x-4x^2y+21\cdot \:4x^2x^2}$

Factor Out Common Term $\bold{4x^2}$

$\bold{4x^2\left(6xy^2-y+21x^2\right)}$

➤ $\boxed{\bold{Mordancy}}$

The price of a ring was decreased by 25% to £390. what was the price before the decrease?

sergiy2304 [10]

Answer:

The original price was 520

Step-by-step explanation:

To find this, we first need to note that we paid 75% of the price. This is because we took 25% off from the original. Now we take the price we paid and divide it by the percentage of it which we paid. This will give us the original price.

390/75% = Total

390/.75 = Total

520 = Total

A brand new truck was purchased for $45.000. A year later the truck was worth $40,480, and the year after that $35.622. If the r

Marat540 [252]

Answer $32,045

Step-by-step explanation: Ok, to get the rate of depreciation all we we have to do is $45 divided by $40.480 you would get 1.1116.

The rate of depreciation: 1.1116

If you do $45,000 divided by 1.1116 you'll get 40,322.

It won't be the exact same answer because you would have to divide for an hour.

Now we can skip to the important part: $35,622 divided by 1.1116 = $32,045

Therefore the truck will be worth $32,045 in 10 years!

I hope this helped
