Answer:

Option (A) and (C).

Step-by-step explanation:

Prime polynomial can't be written as a product of lower degree polynomials.

(A)

8x^2-10x-3

=8x²-6x-4x-3

=2x(4x-3)-1(4x+3)

Here we can't write the polynomial as a product of lower degree.

Therefore it is a prime polynomial.

(B)

8x²+2x-3

=8x²+6x-4x-3

=2x(4x+3)-1(4x+3)

=(4x+3)(2x-1)

Therefore it is not a prime polynomial.

(C)

8x²-6x-3

Therefore it is a prime polynomial.

(D)

8x²+23x-3

=8x²+24x-x-3

=8x(x+3)-1(x+3)

=(x+3)(8x-1)

Therefore it is not a prime polynomial.

How much principle, to the nearest dollar, should you invest at 4 percent in order to have $3000 for a vacation to Europe in 3 y
KiRa [710]

Answer:

Principle should be $2,667

Step-by-step explanation:

We need $3000 for a vacation to Europe in 3 years.

Using amount formula,

A=P(1+r)^t

Where, P is principle (P=?)

A is amount (A=3000)

r is rate of interest (r=0.04)

t is time (t=3)

Substitute the values into formula and solve for P

3000=P(1+0.04)^3

3000=P(1.04)^3

P=\frac{3000}{1.04^3}

P=2666.98

P\approx \$2667

Hence, Principle should be $2,667

Can someone solve m - 4m= -6 step by step please?

Answer:

m = 2

General Formulas and Concepts:

<u>Pre-Algebra</u>

  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

m - 4m = -6

<u>Step 2: Solve for </u><em><u>m</u></em>

  1. Combine like terms:                    -3m = -6
  2. Divide -3 on both sides:              m = 2

<u>Step 3: Check</u>

<em>Plug in m into the original equation to verify it's a solution.</em>

  1. Substitute in <em>m</em>:                     2 - 4(2) = -6
  2. Multiply:                                 2 - 8 = -6
  3. Subtract:                                -6 = -6

Here we see that -6 does indeed equal -6.

∴ m = 2 is the solution to the equation.
