Step-by-step explanation:

Length=2*Width

L=2*W

Perimeter=28.8 cm

Perimeter of a rectangle= 2(Length+Width)

28.8=2(2W+W)\\\\28.8=2(3W)\\\\3W=28.8/2\\\\3W=14.4\\\\W=14.4/3\\\\W=4.8 cm\\\\

Length=2*Width\\\\=2*4.8\\\\=9.6 cm\\\\

Length=9.6 cm\\\\Width=4.8 cm

A physical education teacher plans to divide the seventh graders at Wilson Middle School into teams of equal size of year-ending
Crank

Step-by-step explanation:

Consider the provided information.

The total number of students are: 24+26+21=71

He wants each team will have the same number of students between 5 and 9.

The number between 5 to 9 are 6, 7 and 8.

The number 71 is a prime number so we need to divide the 71 students in group so that minimum students left without team.

Dividing 6 students in each group.

Number of teams: \frac{71}{6} = 11 teams and 5 students.

Dividing 7 students in each group.

Number of teams: \frac{71}{7} = 10 teams and 1 students.

Dividing 8 students in each group.

Number of teams: \frac{71}{8} = 8 teams and 7 students.

Thus, we can not divide 71 students into equal teams, but 70 divided by 7 gives the least students left out i.e 10 teams each with 7 students and only 1 student will remain at last.

The work of a student trying to solve the equation 3(4x − 2) = 9 + 2x + 5 is shown below:
galina1969 [7]
Step 1 gives you 
3*(4x - 2) on the left hand side.

When you remove the brackets what you get is
3*4x - 3*2
12 x - 6 You have to distribute on both sides of the plus sign. The answer is the second one down.

So the answer is 2) <<<< answer.
