Factor completely. 2x^4+4x^3-30x^2

kramer

Answer:

Step-by-step explanation:

2x⁴ + 4x³ - 30x² = 2x²*(x² + 2x - 15)

x² + 2x - 15

Sum = 2

Product = -15

Factors = 5 ; (-3)

x² + 2x - 15 = x² + 5x - 3x - 3 *5

= x(x + 5) - 3(x + 5)

= (x + 5)(x - 3)

2x⁴ + 4x³ - 30x² = (2x²) (x + 5)(x - 3)

The approximate number of Calories, C , that an animal needs each day is given by C=72m^3/4 , where m is the animal's mass in ki

Arlecino [84]

Answer:

576 Calories a 16 kilogram dog needs each day.

Step-by-step explanation:

The approximate number of Calories, C , that an animal needs each day is given by $C=72m^{3/4}$ ,

where m is the animal's mass in kilograms.

now we find the number of Calories that a 16 kilogram dog needs each day.

we are given with m=16

So plug in 16 for m in the given equation

$C=72m^{3/4}\\C=72(16)^{3/4}\\C=72(2^4)^{3/4}\\C=72(2^3)\\C= 576$

576 Calories a 16 kilogram dog needs each day.
