Answer:

\sf\longmapsto \: 38

Step by step explanation:

\sf\longmapsto \:  2a² + 2ab +3-ab

\sf\longmapsto \:  2a² + 3 + ab (2-1)

\sf\longmapsto \: 2a² + 3 + ab (1)

\sf\longmapsto \:  2a² + 3 + ab

\sf\longmapsto \:  2a² + ab + 3

  • Putting a = 5 b = - 3

\sf\longmapsto \: 2(5) {}^{2}  + (5) (-3) +3

\sf\longmapsto \:  2 (25) - 15 + 3

\sf\longmapsto \: 50 - 12

\sf\longmapsto \: 38

(5x-25)(x+4)=0<br> What’s the answer
NemiM [27]

Answer:

x = - 4, x = 5

Step-by-step explanation:

(5x - 25)(x + 4) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

5x - 25 = 0 ⇒ 5x = 25 ⇒ x = 5

Esther has a farm.
Gnesinka [82]

Here, we are required bro determine how many worker Esther needs to employ to pick the same 600kg of onions in 3 hours as compared to 4 hours from last year.

This year, she needs to employ 32 workers to pick a total of 600kg of onions in 3 hours.

According to the data given, the total quantity of onions to be picked still remains 600 kg as from last year, only that she needs it done in 3 hours now.

Therefore,

  • Since 24 workers finished the work in 4 hours,
  • This means that 96 workers are needed to finish the work in 1 hour( from 24×4 = 96).

Therefore, since the work needs to be done in 3 hours this year, This means that it can be shared between X no. of workers.

  • Where X = 96/3= 32

Therefore, this year she needs to employ 32 workers to pick a total of 600kg of onions in 3 hours.

A scale on a map shows that 2.52.52, point, 5 centimeters represents 151515 kilometers.
Dmitry_Shevchenko [17]

Answer:

  105 km

Step-by-step explanation:

Written as a proportion, the ratio of km to cm will be the same for both distances:

  (x km)/(17.5 cm) = (15 km)/(2.5 cm)

  x km = (15 km)(17.5/2.5) = 105 km

105 actual kilometers are represented by 17.5 cm on the map.
