When you cannot simplify it further. The terms have no common factor besides 1 and A plus C does not have two numbers that multiply to the total and equal C.
Answer:
<h2>The area of the base is 144 square inches.</h2><h2>The area of each triangular face is 66 square inches.</h2><h2>Grabiel needs 408 square inches of paint.</h2>
Step-by-step explanation:
The complete problem is attached.
Notice that the figure is a square pyramid, where its base dimensions are 12 inches by 12 inches, which represents an area of

The slant height of the pyramid is 11 inches, which allow us to find the area of each triangle face

But there are four triangle faces, so
.
Therefore, the area of each triangular face is 66 square inches.
So, the total surface area would be the sum

Therefore, Gabriel needs 408 square inches to paint the whole model.

Answer:
$4.257
Step-by-step explanation:
Given:
Items delivered per hour = 14
Fixed hourly costs = $47
variable cost = $0.90
Now,
at breakeven point, the profit = 0
or
Total revenue = total cost
let the charge at breakeven point be 'x'
thus,
x × 14 = $47 + ($0.90 × 14)
or
x × 14 = $47 + $12.6
14x = $59.6
or
x = $4.257
Hence, the breakeven charges are $4.257
X = [-(-8) +/- sqrt((-8)^2 -4*41)] / 2
x = ( 8 + sqrt (-100) / 2 and (8 - sqrt(-100) / 2
