Answer:

1863 m²

Step-by-step explanation:

Multiply 69 by 31

69 • 31 = 2139

Multiply 23 by 12

23 • 12 = 276

Subtract 276 from 2139

2139 - 276 = 1863

Answer is 1863 m²

Answer:

1863 m^2

Step-by-step explanation:

We break down the complex figure into simpler parts, find the areas of the parts, and then sum up the results.

Deleting the entire 23 m-wide vertical middle part, we end up with a rectangle

31 m high and (69 - 23) m wide:  31 m by 46 m.  The area of this rectangle is (31 m)(46 m) = 1426 m^2.

Next, we find the are of that middle part we deleted earlier.  Its height is (31 - 12) m and its width is 23 m.  Thus, this area is 19 m by 23 m, or 437 m^2.

The total area of the figure is (1426 + 437) m^2, or 1863 m^2.

The sum of three consecutive even integers is -78. What is the smallest integer? Show all working outs (5)
svet-max [94.6K]

Answer:

The smallest integer is -27 and the integers are -27, -26, and -25

Step-by-step explanation:

We can represent this with:

x + x - 1 + x - 2 = -78

Simplify.

3x - 3 = -78

Add 3 to both sides.

3x = -75

Divide both sides by 3.

x = -25

So, the first integer is -25.

Subtract two to get the smallest integer.

-25 - 2 = - 27
