Find the surface area of the prism.
Otrada [13]
The dimensions of the prism are 3 m by 4 m by 5 m.

Area = 2(3 * 4 + 3 * 5 + 4 * 5) = 2(12 + 15 + 20) = 2(47) = 94 m^2

Find the degree and leading coefficient of the polynomial.<br> -12+18x^4+15x^3+16x^2
Lostsunrise [7]

Answer:

  • degree 4
  • leading coefficient 18

Step-by-step explanation:

The degrees of the terms in the order they are written (exponent of the variable) are: 0, 4, 3, 2.

The highest degree is that of the second term, so that is the degree of the polynomial, 4.

The leading coefficient is the coefficient of that term: 18.

Use completing the square to solve this quadratic equation.
borishaifa [10]

Step-by-step explanation:

x² + 6x + 9 = 2

(x + 3)² = 2

x + 3 = ±sqrt(2)

x = -3 ± sqrt(2)

so, B and D are correct.

control :

(-3 + sqrt(2))² + 6(-3 + sqrt(2)) + 9 = 2

9 + 2 - 6sqrt(2) - 18 + 6sqrt(2) + 9 = 2

2 = 2

correct

(-3 - sqrt(2))² + 6(-3 - sqrt(2)) + 9 = 2

9 + 2 + 6sqrt(2) - 18 - 6sqrt(2) + 9 = 2

2 = 2

correct

(3 + sqrt(2))² + 6(3 + sqrt(2)) + 9 = 2

9 + 2 + 6sqrt(2) + 18 + 6sqrt(2) + 9 = 2

38 + 12sqrt(2) = 2

wrong.

(3 - sqrt(2))² + 6(3 - sqrt(2)) + 9 = 2

9 + 2 - 6sqrt(2) + 18 - 6sqrt(2) + 9 = 2

38 - 12sqrt(2) = 2

wrong.
