R = kp/st
18 = 12k/(1/6 x 2)
18 = 12k/(1/3)
18 = 36k
k = 18/36 = 1/2

Why is the polynomial, 4x^2y + 5xy classified as a 3rd degree binomial?
Ronch [10]
The polynomial has two terms. The exponent of the first term is two. The exponent of the second term would be 1 because 5xy^1 is equal to 5xy.

What are the solutions of the equation x4+6x^2+5=0? Use substitution to solve
Nataly_w [17]

Answer:

+ or - square root of 5, and + or - i

Step-by-step explanation:

(x^2 + 5)(x^2 + 1)= 0

Set each set of parentheses equal to zero:

x^2 + 5 = 0; x^2 = -5, so x will equal plus or minus i times the square root of 5.

X^2 +1 = 0; x^2 = -1, so x will equal plus or minus i times the square root of one, which is just i

Which expression is a difference of squares with a factor of 2x5?
Sedbober [7]

Answer:

{( \sqrt{3.5} })^{2}  -  {( \sqrt{1.5} )}^{2}

Step-by-step explanation:

The difference of two squares identity is

{x}^{2}   -  {y}^{2}  = (x  - y)(x + y)

When we let

\sqrt{3.5}

and

\sqrt{1.5}

, we get:

{( \sqrt{3.5} )}^{2}  -  {( \sqrt{1.5}) }^{2}  = (3.5 - 1.5)(3.5 + 1.5)

This will simplify to give us the required factors

{( \sqrt{3.5} )}^{2}  -  {( \sqrt{1.5}) }^{2}  =2 \times 5
