You just look at each place value and add them together.
8 is in the thousands place, which is 8,000. 3 is in the hundred place, which gives you 300. The 7 is in the tens place, which gives you 70. The 4 is in the ones place, which gives you 4. Now, you need to combine them together.
8,000 + 300 + 70 + 4
8,374 or 8374

A fence is to be built to enclose a rectangular area of 800 square feet. The fence along three sides is to be made of material t
myrzilka [38]

Answer:

dc/dx = 0 when x = 20. hence fence is 20×40

Step-by-step explanation:

Given data:

Rectangular Area = 800 ft^2

three side material cost = $5 per ft

fourth side material cost is $15 per ft

let expensive side is x and other dimension assume to be y

Then cost is c

c = 5(x+ 2y) + 15 x

xy = 800, so y = 800/x

c =5(x+ 1600/x^2) + 15x

for minimum when dc/dx = 0

\frac{dc}{dx} = 5(1-\frac{1600}{x^2}) + 15 = 0

5(1-\frac{1600}{x^2}) +  15 = 0

(1-\frac{1600}{x^2}) + 3 = 0

(1-\frac{1600}{x^2}) = - 3

x^2 - 1600 = -3x^2

4x^2 - 1600 = 0

(2x-40)(2x+40) = 0

x = 20

dc/dx = 0 when x = 20. hence fence is 20×40
