The three lengths are 3x, 6x, 8x.
The perimeter of a triangle is the sum of all lengths:
3x + 6x + 8x = 520.
Solving for x,
17x = 520
x = 30.59 cm
So the three lengths are
3(30.59) = 91.77 cm
6(30.59) = 183.54 cm
8(30.59) = 244.72 cm

Answer: Choice D</h3>
Explanation:
The first term has its exponents add to 1+2 = 3
The second term has its exponents add to 1+1 = 2
The third term can be written as -2x^0y^0, and those exponents add to 0
The sums count down: 3, 2, 0
So standard form means we write the terms with the largest degree sums first, then second largest and so on.
Answer:
Y=x+3
Step-by-step explanation:
we have :
x1= -7
y1= -4
m=1
as we know Y-y1=m(X-x1)
Y+4=(X+7)
Y+4=X+7
Y=X+7-4
<u>Y=X+3</u>
