The answer is the second choice, or B; 240 ft^2.

You have to find the area of all four triangles and just add those all together. 

Two of the triangles have an area of 
5*16=80
Multiply that by two
80*2=160

The other two smaller triangles have an area of 
8*5=40
Multiply that by 2 also
40*2=80

Add 160+80 and the answer is 240.

Three consecutive integers have a sum of 255 find the integers
GaryK [48]

Answer:

Step-by-step explanation:

Givens

Let the smallest integer = x - 1    (You'll see why in a moment).

Let the middle integer = x

Let the largest ingeger = x + 1

Equation

x - 1 + x + x + 1 = 255

Solution

Combine like terms on the left.

3x - 1 + 1 = 255

3x = 255                      Divide by 3

3x/3 = 255/3

x = 85

So the smallest number is  84

The middle number is        85

The largest number is    <u>    86</u>

Total                                  255

Do you see why I made the smallest number x - 1?

It is because the -1 and the plus 1 cancel out.

Please realize the question says consecutive integers. It does not say consecutive odd or consecutive even integers.

cupoosta [38]

Answer:

square rooted numbers like the square root of 2 are irrational because when calculated they don't equal a whole number.

Step-by-step explanation:

3+5√3 = 11.66   // not whole - irrational

√2 =  1.4 // not whole - irrational

√25 = 5 // whole - rational
