Answer:
I don't understand the language but I can do it
Surface area = area of 3 rectangles + 2 triangles
= 3*(3*7) + 2 * ( 1/2 * 3 * 2.6)
= 63 + 2* 3.9
= 70.8 in^2
Cost per gallon is found by dividing the cost by the number of gallons.
$43.95/16.1 ≈ $2.7298137
Rounded to hundredths, this is $2.73.
Answer:
Minimum value of function
is 63 occurs at point (3,6).
Step-by-step explanation:
To minimize :

Subject to constraints:

Eq (1) is in blue in figure attached and region satisfying (1) is on left of blue line
Eq (2) is in green in figure attached and region satisfying (2) is below the green line
Considering
, corresponding coordinates point to draw line are (0,9) and (9,0).
Eq (3) makes line in orange in figure attached and region satisfying (3) is above the orange line
Feasible region is in triangle ABC with common points A(0,9), B(3,9) and C(3,6)
Now calculate the value of function to be minimized at each of these points.

at A(0,9)

at B(3,9)

at C(3,6)

Minimum value of function
is 63 occurs at point C (3,6).
Answer: x=5
Step-by-step explanation:
If you break the fraction into a whole number it would be 5 and 10 minus 5 is 5. so x=5
