Answer:

B. 288 In

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    x*(x-2)-(288)=0

 x • (x - 2) -  288  = 0

Find two factors of  -288  whose sum equals the coefficient of the middle term, which is   -2 .

     -288    +    1    =    -287

     -144    +    2    =    -142

     -96    +    3    =    -93

     -72    +    4    =    -68

     -48    +    6    =    -42

     -36    +    8    =    -28

     -32    +    9    =    -23

     -24    +    12    =    -12

     -18    +    16    =    -2    That's it

Answer: 288

If you can walk 5.3 miles in 2.5 hours, how many minutes does it take to walk 3.18 miles? Round to 1 decimal.
Oksana_A [137]

Answer:

90min

Step-by-step explanation:

we can solve the first part by means of the rule of three:

5.3miles ----2.5 hour

3.18miles----x

then

x=\frac{3.18*2.5}{5.3} \\x=\frac{7.95}{5.3} \\x=1.5 hours

Now we must convert hours to minutes:

1.5 hours = 1.5hours (1)

1.5 hours =1.5 hours \frac{60min}{1 hours}

1.5 hours =(1.5)(60) min

1,.5 hours =90min

f(-3) = 18

Step-by-step explanation:

We need just substitute x with (-3) and calculate it.

f(-3) = (-3)² -2*(-3) + 3 = 9 + 6 +3 = 18
