Answer:

a) 2a + 6(a - 2) = 44

b) short side = 7 cm long side = 15 cm

Step-by-step explanation:

a) (2 x a) + [2 x 3(a - 2)] = 44

2a + 6(a - 2) = 44

b) 2a + 6(a - 2) = 44

2a + 6a - 12 = 44

8a -12 = 44

8a = 56

a = 7

Therefore, one side has length of 7 cm, and the other has

length of 3(7 - 2) = 15 cm.

Hope this helps!

soldier1979 [14.2K]

Answer:

$\frac{9}{20}$ students.

Step-by-step explanation:

We have been given that of the students that attended Roosevelt Elementary 6/8 of the school play a sport. Of the students are playing a sport 3/5 of the students are also involved in the drama club.

To find the students are both play a sport and a part of the drama club, we need to find 3/5 part of 6/8 as:

$\text{Students who play a sport and a part of the drama club}=\frac{6}{8}\times \frac{3}{5}$

$\text{Students who play a sport and a part of the drama club}=\frac{3}{4}\times \frac{3}{5}$

$\text{Students who play a sport and a part of the drama club}=\frac{3\times 3}{4\times 5}$

$\text{Students who play a sport and a part of the drama club}=\frac{9}{20}$

Therefore, $\frac{9}{20}$ students play sport and part of the drama club.
