snow_lady [41]

Answer:

542 minutes

Step-by-step explanation:

currently our mean is =530

i got that by adding all the number out which equal too =2,650

and divide it by how many number there are which is 5

2,650/5=530

After some trial and error i found it

so you add 494+690+502+478+486+542=3,192

3,192/6=532

and that was our goal

so the 6th month she talked on the phone for 542 minutes

How to answer this on descending powers of x please help pretty please
zheka24 [161]

Answer:  25x² - 64

<u>Step-by-step explanation:</u>

  (5x + 8)(5x - 8)

=        5x(5x - 8)   +    8(5x - 8)

=      25x² - 40x    +    40x - 64

=      25x²         + 0x           - 64

=              \large\boxed{25x^2-64}

NOTE: descending powers means the biggest exponent goes first, then the next biggest exponent, etc.

For example: x⁴ then x³ then x² then x then the number (which is actually x⁰)
