Wen is factoring the polynomial, which has four terms.
Firdavs [7]

Answer:

2x(x + 3)(2x - 1)

Step-by-step explanation:

Given

4x³ + 10x² - 6x ← factor out 2x from each term

= 2x(2x² + 5x - 3) ← factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 3 = - 6 and sum = + 5

The factors are + 6 and - 1

Use these factors to split the x- term

2x² + 6x - x - 3 ( factor the first/second and third/fourth terms )

= 2x(x + 3) - 1(x + 3) ← factor out (x + 3) from each term

= (x + 3)(2x - 1)

Thus

4x³ + 10x² - 6x = 2x(x + 3)(2x - 1) ← in factored form

In the year 2005, a total of 750 fish were introduced into a manmade lake. The fish population was expected to grow at a rate of
tangare [24]
The population of the fish is given by P(t) = 750(1 + 0.083)^t; where t is the number of years after 2005.
Here, t = 2050 - 2005 = 45

Population in 2050 = 750(1.083)^45 = 750(36.16) = 27,123

viktelen [127]

Answer:

7

Step-by-step explanation:

→ Find the scale factor

30 ÷ 25 = 1.2

→ Multiply answer by 20

20 × 1.2 = 24

→ Equate equation to 24

4x - 4 = 24

→ Add 4 to both sides

4x = 28

→ Divide both sides by 4

x = 7
