**Answer:**

7.31 times.

**Step-by-step explanation:**

We have been given that Grand Canyon is approximately 29 kilometers long. Mariner Valley is a canyon on Mars that is approximately 212 kilometers long.

To find the number of times Mariner Valley is longer than the Grand Canyon, we will divide 212 by 29.

**Therefore, the Mariner Valley is 7.31 times longer than the Grand Canyon.**

Grand Canyon = 29 km

Mariner Valley = 212 km

Number of times longer = 212 ÷ 29 = 7.31 times (Nearest hundredth)

**Answer: 7.31 times**

Mariner Valley = 212 km

Number of times longer = 212 ÷ 29 = 7.31 times (Nearest hundredth)

__Cjhoward1__, it isn't nice to call someone a nerd. I mean, sure a nerd is a smart person who really cares about school but it has a bad connotation and isn't the nicest thing to say to someone. If you meant it in a good way, then please accept my apologies but other ways I think you should think twice before you say something like that. And if you did think twice maybe you should think 3 times before you say something. It can be really mean. You may not notice it but it can hurt peoples feelings. Anyway. Have a good day!

6x-9=45 is the answer

Solution 2

Whats the question i cant see it

Question

What time what equals 92

Solution 1

Multiplication is the taking of a number, and adding an X amount of that number to itself. In this case, the number is 92.

X*Y=92

There are many possibilities for the answer, so we will simplify.

92 divided by two = 41, therefore 41 * 2 = 92.

**41 and two are one of a few answer pairs. **

X*Y=92

There are many possibilities for the answer, so we will simplify.

92 divided by two = 41, therefore 41 * 2 = 92.

Question

Factor completely 2x3 + 10x2 + 4x + 20. 2(x3 + 5x2 + 2x + 10)
2[(x + 5)(x2 + 2)]
(2x + 10)(x2 + 2)
(x + 5)(2x2 + 4)

Solution 1

**Answer:**

**Step-by-step explanation:**

Alright, lets get started.

The given expression is :

taking 2 common factor

**So, the correct answer is option B : answer**

Hope it will help :)

Solution 2

2x^3 + 10x^2 + 4x + 20

= 2(x^3 + 5x^2 + 2x + 10)

= 2[x^2(x + 5) + 2(x + 5)]

= 2[(x+5)(x^2 + 2)]

answer

2[(x + 5)(x^2 + 2)]

= 2(x^3 + 5x^2 + 2x + 10)

= 2[x^2(x + 5) + 2(x + 5)]

= 2[(x+5)(x^2 + 2)]

answer

2[(x + 5)(x^2 + 2)]

Question

juan received a paycheck of $185 from his job he spend 1/4 of his paycheck on clothes and then spend $8.25 for Lunch how much of his paycheck did juan spend? someone HELP

Solution 1

He receives $185

He spent 1/4 of his paycheck on clothes, that is, = 1/4 *185 = 46.25

$8.25 for lunch.

So he spent $ 54.50 of his salary

He spent 1/4 of his paycheck on clothes, that is, = 1/4 *185 = 46.25

$8.25 for lunch.

Total spent = 8.25 + 46.25 = 54.50.

So he spent $ 54.50 of his salary

Solution 2

1/4 = 46.25

lunch = 8.25

add them together

50.50

Now take that away from 185 and that makes
