enyata [817]

Answer:

a) 2x + 1, 4x + 7

b) L = 19 cm, W = 7 cm, A = 133 cm^2

Step-by-step explanation:

8x^2 + 18x + 7

ax^2 + bx + c

ac = 8 * 7 = 56

56 = 4 * 14

8x^2 + 18x + 7 =

= 8x^2 + 14x + 4x + 7

= 2x(4x + 7) + 1(4x + 7)

= (2x + 1)(4x + 7)

a) 2x + 1, 4x + 7

2(3) + 1 = 7

4(3) + 7 = 19

A = LW = 19(7) = 133

77julia77 [94]

Answer:

Distance covered by Reuben jogging in 4 calendar weeks = 61.2 miles

Step-by-step explanation:

Distance covered by Reuben jogging every weekday = 2.25 miles

Distance covered by Reuben jogging every weekends is 1.8 times as far as he covers in weekdays to nearest hundred.

To find Reuben jogs in 4 calendar weeks.

Solution:

Distance covered by Reuben jogging every weekends = $1.8\times 2.25\ miles= 4.05\ miles$

There are 5 weekdays in a week.

Thus, total distance traveled in weekdays = $2.25\times 5=11.25\ miles$

Distance jogged in a week = $4.05\ miles + 11.25\ miles =15.3\ miles$

Using unitary method to find distance jogged in 4 weeks.

If Reuben jogs 15.3 miles in a week

Thus, in 4 weeks he will jog = $15.3\ miles \times 4 =61.2\ miles$

A tire manufacturing company has fixed cost of $20,000 and production cost of $60 per tire. If the tires are sold at $100 each,

miskamm [114]

Answer:

A loss of 8,000

Step-by-step explanation:

If each tire is sold at $100 and 300 tires are sold then the amount gained is 30,000.

Cost of production for the tires is 18,000, so now we must subtract 18,000 from 30,000 to get 12,000.

Finally, we take away the fixed cost (20,000) from 12,000 to get -8,000.
