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 :)
Answer: 8 short response questions and 12 multiple choice questions
Step-by-step explanation:
Let m represent multiple choice questions
Let s represent short response questions
m + s = 20 --> Amount of questions
3 m + 8 s = 100 --> Total number of points for each question
Solve using elimination, multiply the first equation by -3
-3m-3s=-60
3 m + 8 s = 100
----------------------
5s=40
s=8
m+8=20
m=20-8
m=12
Therefore, there are 8 short response questions and 12 multiple choice questions
A You have to count up to the 1 and it takes 4 spaces to get there
3, they developed a new technology that allows them to produce more of both goods
In a 45 45 90 triangle, the hypotenuse = leg * square root of 2
So x = 18*sq root of (3) * sq root of (2)
x = 18 * sq root of 6
