Answer:

Step-by-step explanation:

mono means one so there must only be one term, the number in front of the variable is the coefficient, n being squared makes it to the second degree

I assume it is the last one, 3n^2, because the degree is the exponent, which is two and the three is the coefficient, which is next to the variable, plus it is a monomial, so there is only one term, eliminating the first two, the third one is just reversed. Therefore, the answer should be the last one. Hope this helps. :)

Answer:

1) $(-y^2-4y-8+4y^2+6y-3)$

2) $32x^5y^4z^2$

3) $x^3-9x^2+14x+24$

Step-by-step explanation:

Given the expression we have to simplify the expression

1) $(-y^2-4y-8)-(-4y^2-6y+3)$

⇒ $(-y^2-4y-8+4y^2+6y-3)$

Combining like terms, we get

⇒ $3y^2+2y-11$

2.) $(2x^2y^3z^2)(4xy.4x^2)$

⇒ $(2x^2y^3z^2)(16x^3y)$

⇒ $32x^5y^4z^2$

3.) $(x-4)(x^2-5x-6)$

⇒ $x^3-5x^2-6x-4x^2+20x+24$

⇒ $x^3-9x^2+14x+24$

Which equation shows the inverse property of multiplication?

serious [3.7K]

Answer:

Step-by-step explanation:

The options are:

A. 4 + (-4) = 0

B. -8 + (-3) = -3 + (-8)

C. 2 × 1/2 = 1

D. 8/5 + 0 = 8/5

The inverse property of multiplication states that the product of a number and its inverse is one.

The inverse of 2 is 1/2. The multiplication of 2 × 1/2 = 1 , as the property states.

HELP IM TIMED I WILL GIVE YOU BRAINLIEST!!!! The ordered pairs graphed are all equivalent ratios. What ordered pair is missing f

irina [24]

The answer is D because The ordered pairs graphed are (2,3), (6,9), and (8,12). They all have a ratio of 2 to 3. Which means each point is 2 larger on the x-axis and 3 larger on the y-axis than the previous point. The point that is missing is (4,6) since 2 + 2 = 4 and 3 + 3 = 6.

1. Solve proportion 12/15 = 18/b

omeli [17]

We solve the as follows:

1. Solve proportion 12/15 = 18/b
( 12/15 = 18/b ) b
( 12b/15 = 18 ) 15/12
b = 18(15/12)
b = 45/2

2. Solve equations

A. -x + 4 = x +6
-x + 4 - x = x +6 - x
-2x + 4 - 4 = 6 - 4
-2x = 2
x = -1

B. 5n + 7 =7(n+1) -2n
5n + 7 = 7n + 7 - 2n
5n -7n + 2n = 7 - 7
0 = 0

C. -4(p+2) + 8 = 2(p-1) - 7p + 15
-4p - 8 + 8 = 2p - 2 - 7p + 15
-4p + 7p - 2p = -2 + 15 + 8 - 8
p =13

3. Solve a/b x - c = 0 for x
a/b x - c = 0
( a/b x = c ) b/a
x = bc / a
