How to find the perimeter of a square one side is 10x other side is 6x+8?

To find the perimeter of the square, you add all four sides together:
10x + 10x + (6x + 8) + (6x + 8)
20x + 12x + 16 = P
32x + 16 = P

you have to find x to get the actual perimeter. Since the shape is a square, all 4 sides are equal, so you can set 10x and (6x + 8) as equal to each other.
10x = 6x + 8
4x = 8
x = 2

Now you just plug in x and finish the rest of the problem, and you have the answer:
32(2) + 16 = P
64 + 16 = P
P = 80

(if you find this helpful, marking this as the brainliest answer would make my day :)

Show work. How do you solve for x degree if the hyp= 7 and the opp= 4? (round to the nearest degree)
Stolb23 [73]
So we have the opp and hyp, use sine.

sinx=O/H
sinx=4/7
inverse sine to isolate x.
x=sin⁻¹(4/7)
x=34.84

On August 1, 2021, a company accepts an $8,000, 9-month note receivable. For 2021, the company reports interest revenue of $200.
erastova [34]

Answer:

6%

Step-by-step explanation:

We have to calculate the interest rate in the note, we must follow the following steps, calculate the amount of time remaining from the year 2021, as follows:

interest is for 5 months i.e. from Aug 01 to Dec 31 for year 2021 , so it means it would be 5/12 months.

We have to calculate the interest as follows:

I = P * R * T

We replace:

200 = 8000 * R * 5/12

we solve for R

200 * 12/5 = 8000 * R

R * 8000 = 480

R = 480/8000

R = 0.06

Which means that the interest rate on the note is 6%

11b-7-3n+8-5b+9n what is the answer
Sergio [31]

Answer:

6 n + 6 b + 1

Step-by-step explanation:

Simplify the following:

11 b - 7 - 3 n + 8 - 5 b + 9 n

Grouping like terms, 11 b - 7 - 3 n + 8 - 5 b + 9 n = (9 n - 3 n) + (11 b - 5 b) + (8 - 7):

(9 n - 3 n) + (11 b - 5 b) + (8 - 7)

9 n - 3 n = 6 n:

6 n + (11 b - 5 b) + (8 - 7)

11 b - 5 b = 6 b:

6 n + 6 b + (8 - 7)

8 - 7 = 1:

Answer: 6 n + 6 b + 1
