The ratio between the lengths of similar prisms is

$k=\dfrac{6}{5}$ .

If the surface area of small prism is 572 sq. cm, then

$\dfrac{SA_{large}}{SA_{small}} =k^2,\\ \dfrac{SA_{large}}{572} =(\dfrac{6}{5})^2=\dfrac{36}{25} ,\\ SA_{large}=\dfrac{572\cdot 36}{25} =823.68\approx 823,7$ sq. m.

Answer: 823.7 sq. m.

Which of the following companies offers the greatest total employment compensation? Company A Gross pay $38,200 Insurance $3,500

spayn [35]

Answer:

Company C offers the greatest total employment compensation.

Step-by-step explanation:

Now we calculate the greatest total employment compensation as follows:

Company A :

Gross pay - $38,200

Insurance - $3,500

Paid time off - $4,100

Total compensation = 38,200 + 3,500 + 4,100 = $45,800

Company B :

Gross pay - $39,000

Total employee benefit - 20% of 39,000 (0.20 × 3900) = $7,800

Job expenses - $700

Total compensation = 39,000 + 7,800 + 700 = $47,500

Company C :

Gross pay - $39,900

Insurance - $3,200

paid time off - $3,900

Job expenses- $1,000

Total compensation = 39,900 + 3,200 + 3,900 + 1,000 = $48,000

Company D:

Gross pay - $39,400

total employee benefits - 18% of 39,400 (0.18 × 39,400) = $7,092

Total compensation = 39,400 + 7,092 = $46,492

Therefore company c offers the greatest total employment compensation.

Which expression completes the factored form of this quadratic expression? x2 + 4x – 5

Advocard [28]

Find factors of -5 that, when added together, will give 4

x² + 4x - 5
x 5
x -1

(x + 5)(x -1)

Using the FOIL method (First, Outside, Inside, Last), we can get the question again.

x(x) = x²
x(-1) = -x
5(x) = 5x
5(-1) = -5

x² - x + 5x - 5
x² + 4x - 5

(x + 5) (x - 1) is your answers

however, i believe it is only asking for one. Therefore, because (x - 1) is a choice, (x - 1) should be your answer

hope this helps
