Which expression is equivalent to 7x , if b > 0?
AlladinOne [14]
<h3>Answer:  Choice C</h3>

Work Shown:

7x^2*\sqrt{2x^4}*6\sqrt{2x^{12}}\\\\7*6x^2*\sqrt{2x^4*2x^{12}}\\\\42x^2*\sqrt{4x^{4+12}}\\\\42x^2*\sqrt{4x^{16}}\\\\42x^2*\sqrt{(2x^8)^2}\\\\42x^2*(2x^8)\\\\42*2x^{2+8}\\\\84x^{10}\\\\

So that's why the answer is choice C

The requirement that x is nonzero isn't technically necessary. The original expression simplifies to choice C even when x = 0 is the case. Also, we don't have issues such as division by zero errors that could arise. It's a bit curious why your teacher put in that condition.

In which quadrant is the point (0,7) located? Explain your answer.

0, 7 is placed in the top middle quadrant because the x value is 0, therefore it does not move left or right, and y is placed up into the middle. Mark Branliest. :-)

Tanner has 200 baseball cards. Of those, 42% are in mint condition. How many of the cars are in mint condition?
Thepotemich [5.8K]

The number of cars that are in mint condition are = 84

<h3>Number of cars in mint condition</h3>

The number of baseball cards owned by Tanner = 200

The percentage of baseball cards that are in mint condition = 42%

Therefore the number of cars in mint condition

=

\frac{42}{100}  \times  \frac{200}{1}

\frac{8400}{100}

= 84

Therefore, the number of cars that are in mint condition are = 84

A board 91 cm long is to be cut into two parts so that the longer part is 10 cm more than twice as long as the shorter part. Fin
mojhsa [17]

Answer:

The parts are 27 cm and 64 cm long.

Step-by-step explanation:

Let the shorter part be x.

"The longer part is 10 cm more than twice as long as the shorter part."

shorter part: x

longer part: 2x + 10

total length: x + 2x + 10

total length: 91

x + 2x + 10 = 91

3x + 10 = 91

3x = 81

x = 27

2x + 10 = 2(27) + 10 = 54 + 10 = 64

Answer: The parts are 27 cm and 64 cm long.
