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

Answer: 5n-6=39;n=9
Step-by-step explanation:
The product of: indicates multiplication
A number: indicates you need a variable (n)
And five: indicates what your multiplying (5)
Decreased by six: indicate your subtracting 6
Is thirty nine: indicates your answer is 39
Now solve using inverse operations
5n-6=39
<u> +6 +6</u>
<u>5n</u>=<u>45</u>
5 5
n=9
Answer:
line r: y=-2x-2
line s: -2x+1
lime t: -2x+3
Step-by-step explanation:
every slope must be -2 since that's stated in the question
to find b in y=mx+b, you substitute 0 for x and the y coordinate when x is 0 into the equation (for example for slope r, when x is 0 then y is -2, so -2=-2(0)+b) then solve for b (-2=-2(0)+b is -2=b)
basically, b is the y component when x is 0
