Surface Area = lw + ph

Surface Area = (18 x 7) + 12(18 + 18 + 7 + 7)

Surface Area = 126 + 600

Surface Area = 726 cm²

Answer:  726 cm²

andre [41]
- \dfrac{4}{3} x - 6 = -26

//Add 6 to both sides:
- \dfrac{4}{3} x  = -20

//Multiply by -1 on both sides:
\dfrac{4}{3} x  = 20

Multiply by 3 on both sides:
4x  = 60

Divide by 4 on both sides:
x  = 15

Answer: x = 15 (Answer C)

Your friend says that the solutions to the inequality 5x - 14x &lt; - 18 are x ≤2. Solve the inequality correctly. What error di
katrin2010 [14]
<h3>Answer:  x > 2</h3>

Work Shown:

5x - 14x < - 18

-9x < - 18

x > -18/(-9)

x > 2

The inequality sign flips when dividing both sides by a negative number.

Here's another approach you could take.

5x - 14x < - 18

-9x < -18

0 < -18+9x

18 < 9x

9x > 18

x > 18/9

x > 2

It's a slightly longer pathway, but it avoids a sign flip when you divide both sides by the positive number 9.

The sign flip happens two steps earlier when going from 18 < 9x to 9x > 18. In other words, A < B is the same as B > A.

Emery Mining Inc. recently reported $147,500 of sales, $75,500 of operating costs other than depreciation, and $10,200 of deprec
Molodets [167]

Answer:

net income is $48452.81

Step-by-step explanation:

Sales =$147500

subtract operating expenses

-$75500 =$72000

subtract non- operating costs

depreciation -$10200 =$61800

-interest expense payable (16500*7,23%)$1196.25=63603.75

from profit before tax deduct income taxes =63603.75*25%=15150.9375

Net Income is therefore $63603.75-$15150.9375 = $48452.81
