Please solve for X and show step by step equation

Answers

Answer:

6

Step-by-step explanation:

Firstly, this is the pythagoreans theorem a^2+b^2=c^2

Now that we know that, we will solve for x.

(x+2)^2+x^2=100 ( The 100 is just 10 squared )

Finally, you solve for x and get 6.

1/6 represents the 10 out of 6, but it is known as 1 in this answer because it is a choice out of the other 6.

(2m-7)(2m-7)
4m^2 - 14m - 14m + 49
4m^2 - 28m + 49

Answer: 4m²-28m+49

Step-by-step explanation:

(2m-7)² can be written as (2m-7)(2m-7).

You would have to multiply it out like this:

2m times 2m=4m² (2x2=4 and mxm=m²)

2m times -7=-14m (2x-7=-14 then put a m on it)

-7 times 2m=-14m

-7 times -7=49

The equation would then look like this:

4m²-14m-14m+49

Then you would have to collect like terms. Like terms are terms with the same variables and powers. It will then look like this:

4m²-28m+49

Answer:

The first one is proportional and the second one is not. Because for the first one you can see that if you divide the number of pens by the cost you'll get the same answer for every single one. But for the second one if you divide the number of minutes by words typed you get a different answer for each one. You can also see if it's proportional or not if you draw it on the graph and it's a straight line. If it is the relationship is proportional if it isn't it's not proportional. Hope that makes sense :)

Determine whether the relationship between the two quantities shown in the table or graph is linear. If so, find the constant rate of change. If not, explain your reasoning.  1. SOLUTION:  Analyze the table. The rate of change from 5 hours to 8 hours is  or 3 cents per hour. This is the same as therate of change from 8 hours to 12 hours,  or 3 cents per hour, and from 12 hours to 24 hours,  or 3 cents per hour. So, the rate of change is a constant 3¢ per hour. ANSWER:  Yes; the rate of change between cost and time for each hour is a constant 3¢ per hour. e i dont know if this is the answer to ur question but here u go

I don't usually use this website anymore, but here's an answer I found for you.

Answer:

-14.57

Step-by-step explanation:

Subtract -2.67 by 5.95×2 since there were two days it equals -14.57

(Or)

-2.67 + x2 (x =-5.95)

-2.67 + (2*-5.95*) = -14.57

Part 1:

The account will be -14.57 after two days.

Step by step:

What I do is just forget the negatives until the end.

5.95 + 5.95 (two days) + 2.67 = 14.57

Bring back the negative: -14.57

What is the perimeter of this figure?


Use 3.14 for pi.


60.84 m


72.84 m


79.68 m

Answers

Perimeter of figure = 3 sides of rectangle + perimeter of semi-circle.

3 sides of rectangle = 15 + 12 + 15 = 42

Perimeter of semi-circle = πr = 3.14 * 6 = 18.84

In short, Your Answer would be: 42 + 18.84 = 60.84 m
