The correct answer is E.

The commutative property of multiplication states that if you multiply two factors, the result is the same no matter which order you put the terms in.

If the perimeter of a rectangle is 6x^2-2x+14 and the length is x^2-x+8 what is the measure of the width?

s2008m [1.1K]

Answer:

w = 2x^2-2x+15

Step-by-step explanation:

Since the formula to find the perimeter is P=2l+2w, use this to set up your equation:

6x^2-2x+14 = 2(x^2-x+8) + 2w

Then, distribute the 2 to everything inside the parentheses.

6x^2-2x+14 = 2x^2-2x+16 + 2w

Subtract 2x^2-2x+16 from both sides, leaving you:

4x^2-4x+30 = 2w

Divide 2 from both sides.

2x^2-2x+15

The answer is 2x^2-2x+15

A bulletin board has a perimeter of 200 inches. Which equation expresses the area A(w) of the bulletin board as a function of it

o-na [289]

Answer: A(W) = 100W - $W^{2}$

Step-by-step explanation:

The formula for calculating the perimeter is given as :

P = 2 ( L + W )

the perimeter is given as 200 , that is

200 = 2 ( L + W )

Dividing through by 2 , we have

100 = L + W

Make L the subject of the formula ;

L = 100 - W

The formula for the area is given as Length x width , substituting the values , we have :

A = LW , since , L = 100 - W , we have

A = (100- W) (W)

A = 100W - $W^{2}$

Therefore :

A(W) = 100W - $W^{2}$

What is the true solution to the equation below? 2 in e in2×-in e in 10×= in 30 A x=30 B x=75 C x=150 D x=300

hodyreva [135]

Answer:

Option B.

Step-by-step explanation:

Let as consider the given equation:

$2\ln e^{\ln 2x}-\ln e^{\ln 10x}=\ln 30$

It can be written as

$2(\ln 2x)-(\ln 10x)=\ln 30$ $[\because \ln e^a=a]$

$\ln (2x)^2-(\ln 10x)=\ln 30$ $[\because \ln a^b=b\ln a]$

$\ln \dfrac{4x^2}{10x}=\ln 30$ $[\because \ln \dfrac{a}{b}=\ln a-\ln b]$

$\ln \dfrac{2x}{5}=\ln 30$

On comparing both sides, we get

$\dfrac{2x}{5}=30$

Multiply both sides by 5.

$2x=150$

Divide both sides by 2.

$x=75$

Therefore, the correct option is B.
