Take the three numbers, and list all of their prime factors. I'll use 3, 9, and 21 for an example to help.
3: 3
9: 3 x 3
21: 7 x 3
You take the times that a number occurs the most in any of the three numbers and multiply them together. 3 occurs the most in a single number twice, and 7 occurs the most in a number once.
So you'd multiply 3 x 3 x 7 to get 63.

A car rental agency advertised renting a car for $24.95 per day and $0.26 per mile. If Brad rents this car for 3 days, how many

bulgar [2K]

Answer:

481 whole miles

Step-by-step explanation:

Total cost would be 3 x 24.95 + 0.26m, where m is the miles driven.

Total cost has to be under or equal to $200, so

3 x 24.95 + 0.26m <= 200

74.85 + 0.26m <= 200 ( 3 x 24.95)

0.26m <= 125.15 ( subtract 74.85)

m <= 481.35 ( divide 0.26)

We want to factor the following expression:

11Alexandr11 [23.1K]

Answer:

We have $\mathbf{U= 9x^3 \:and\:V=y+1}$

Step-by-step explanation:

We want to factor the expression $81x^6-(y+1)^2$ in the form of (U+V)(U-V)

We need to find U and V

We can use formula : $a^2-b^2=(a+b)(a-b)$

We can write $81x^6$ as $(9x^3)^2$

Now we have the expression:

$81x^6-(y+1)^2\\=(9x^3)^2-(y+1)^2$

Applying formula: $a^2-b^2=(a+b)(a-b)$

$=(9x^3+y+1)(9x^3-(y+1))\\=(9x^3+y+1)(9x^3-y-1)$

So, we have $\mathbf{U= 9x^3 \:and\:V=y+1}$
