<span>The easiest thing to do is convert all the measurements to yards...
 18ft = 6 yards
 6 inch = 1/6 yard     ( 6 inches = 1/2 ft.... so 1/6 yard)
  so the volume is V = 6 x 6 x 1/6
 Then all you do is calculate the cost. I hope this helps you out</span>

Kay [80]

Answer:

x= -8     x=2

Step-by-step explanation:

x^2 +6x - 6 = 10

Subtract 10 from each side

x^2 +6x -16 =0

Factor  what 2 numbers multiply to -16 and add to 6

8*-2 = -16

8-2 = 6

(x+8) (x-2) =0

Using the zero product property

x+8 =0    x-2 =0

x= -8     x=2

A college is hosting an invention camp for middle school students. One of the 1,200 students who attend will receive a laptop at
Ipatiy [6.2K]

Answer: Randomly assign the 1,200 students to <u>6 equal-sized</u> groups. Then select one of the groups and place their names in the bin. Randomly select the winner from the bin.

Step-by-step explanation:

     First, let us see how many bins we will need in total.

1,200 students / 200 notecards per bin = 6 bins

     Now, the first two options do not give all students a fair chance of winning. They are not our answer.

     The last two have a different number of groups. Looking at the calculation we did earlier, we will need 6 equal-sized groups. This means our answer is the last option.
