Answer: n=7+1/2

Step-by-step explanation:

We move all terms to the left:

2n+15-(30)=0

We add all the numbers together, and all the variables

2n-15=0

We move all terms containing n to the left, all other terms to the right

2n=15

n=15/2

n=7+1/2

Solve the equation using square roots
x^2 - 55 = 26

Answers

Answer:

x = ±9

Step-by-step explanation:

x² - 55 = 26

   +55   + 55

     x² = 81

     x = √81

     x = ± 9

Answer:

x = 9, -9

Step-by-step explanation:

x^2 - 55 = 26

x^2 = 81.

Now, you might think that x = 9, but don't be fooled. -9 squared is also equal to 81.

So, x = 9, -9

Solve using proportions.

The triangles are similar, find the length of side (k) using a proportion; having ratios within the two figures.

Note: If someone could please answer before this upcoming Monday.​

Answers

Answer:

7.8 = k

Step-by-step explanation:

Since the figures are similar, we can use proportions

c           k

----- = -------

b            j

Substituting the values in

6.5         k

----- = -------

4          4.8

Using cross products

6.5 * 4.8 = 4k

31.2 = 4k

Divide each side by 4

31.2/4 = 4k/4

7.8 = k

Answers

Answer:

Step-by-step explanation:

Ok so I'm not 100% sure how to solve this but what I would do is use the equation a^2 + b^2 = c^2 this equation is used to solve for the hypotenuse or the longest side of a triangle. To find a^2 you would do (21+15)^2 (Also this symbol ^ is the power symbol) and the answer would be 1296. b^2 would be 25^2 or 625. The equation turns out to be 1296 + 625 = c^2. c^2 (or x in this case) would be 1921. To find just c and not c^2 you would find the square root of 1921 which is 43.8292140016 or if rounded would be 43.8. Also this might not help if I misinterpreted the question...

2. How many solutions to the equation 2x +2 = 2(x+3)
O 1 solution
O Infinitely many solutions
O No solution

Answers

Answer:

O No solution

Step-by-step explanation:

2x +2 = 2(x+3)

Distributer the 2 on the right side.

2x + 2 = 2x + 6

Subtract 2x from both sides.

2 = 6

2 = 6 is a false statement.

Since we did two legal steps to solve the equation, and we ended up with a false statement, that means this equation has no solution.

Answer: O No solution

Find the area of the composite figure

Answers

Step-by-step explanation:

You're only finding half of a circle but since you have 2, it is possible to just do the area of a circle which is [tex]\pi r ^{2} [/tex]

3.5 x 3.5 = 12.25

Because the radius of your circle is 3.5m but there are 2 of them you subtract 7 from 18 which give you 11:

Then you multiply 11 by 7.

= 77

Then add it all together.

[tex]a = (77 + 12.25\pi)m^{2} [/tex]
