Answer:  The correct option is (C) 26.

Step-by-step explanation:  We are given to perform the indicated operation :

E=15-(-11).

We will be using the following rule of addition and subtraction :

a-(-b)=a+b.

Therefore, we get

E=15-(-11)=15+11=26.

Thus, the required value of the given expression is 26.

Option (C) is CORRECT.

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,360 ft Determine the​ flag's width and
just olya [345]

The length of rectangular mosaic flag is 710 feet and width is 470 feet

Step-by-step explanation:

Let l be the length of the flag

and

w be the width

Then according to given statement

l = w+240

Perimeter = 2360 feet

The formula for perimeter is given by:

Perimeter = 2(Length+Width)

Putting values

2360 = 2[w+240+w]\\\frac{2360}{2} = \frac{2[w+240+w]}{2}\\1180 = 2w+240\\1180-240 = 2w+240-240\\940 = 2w

Dividing both sides by 2

\frac{2w}{2} = \frac{940}{2}\\w = 470

The width is 470 feet

Now,

l = w+240\\= 470+240\\=710

Hence,

The length of rectangular mosaic flag is 710 feet and width is 470 feet
