Mathematics
1 answer:
ELEN [110]3 years ago
8 0

Answer:

(3·x^2 - 2·x)·(2·x^2 + 3·x - 1)

= 3·x^2·2·x^2 + 3·x^2·3·x - 3·x^2·1 - 2·x·2·x^2 - 2·x·3·x + 2·x·1

= 6·x^4 + 9·x^3 - 3·x^2 - 4·x^3 - 6·x^2 + 2·x

= 6·x^4 + 5·x^3 - 9·x^2 + 2·x

Answer: 7.5 miles

Step-by-step explanation:

think of it as a triangle; the bold line is the hypotenuse, or x.

 8   |\   x

      |_\              it's not a good triangle but you get the point

       6

and then get out pythagorean theorem: a^2+b^2=c^2

put the numbers in: 8^2 + 6^2 = x^2

do some math:

64+36=x^2

100=x^2 (and then find square root)

10=x

<u>BUT</u>, it said each unit was 3/4 of a mile, so we must multiply 10 by 3/4 to get the actual distance, which is 7.5

ruslelena [56]

Answer:

16 minutes

Step-by-step explanation:

Tom walks for 5 minutes longer than he rides. To figure out the answer, start by subtracting 5:

27 - 5 = 22

Now that you have done this, divide 22 by 2:

22/2 = 11

Now you know that he rode the bus for 11 minutes, and you can add five to the other 11 minutes to know how long he walked:

11 + 5 = 16.
