The answer should be -141
$26.20 minimum cost of option 1
$36.68 minimum cost of option 2
Area₁ = Length x Width
A₁ = 80 x 36
A₁ = 2880 in² * this in only one side of the door.
Total Area = A₁ x 2 sides = 2880 = 5760 in² * only good for 1 coating of paint
Total Area to be coated = 5760 x 2 coats of paint = 11,520 in²
1st option - $10 / gallon and 4400 sq. in.
2nd option - $ 7 / gallon and 2200 sq. in
11,520 / 4400 = 2.62 x $10 = $26.20 minimum cost of option 1
11,520 / 2200 = 5.24 x $ 7 = $36.68 minimum cost of option 2
For the second question the answer should be 50×6=300+50=350 letters for Matilda. And for Lorraine It would be 40×6=240+80=320
Answer:
f(g(n)) = 3*n^2 + 9
Step-by-step explanation:
This is function composition.
so
f (g(n) ) = 3 *( n^2 + 4) - 3
simplify:
f (g(n) ) = 3 *n^2 + 12 - 3 = 3*n^2 + 9
