I think it is 568 if I’m not mistaken
Answer:
<h2>46 cm</h2>
Step-by-step explanation:
first ,we use the Pythagorean theorem to determine the width:
width = √(17^2-15^2) = 8
then
perimeter = 2(width+lengt) = 2(8 + 15) = 2×23 = 46
1)
-2(3x+4)=-6x-8≠-6x+8
2)
2(-3x+4)=-6x+8
3)
5(x+1)-11x+3=5x+5-11x+3=-6x+8
4)
x+2-7x+6=-6x+8
5)
8-6x=-6x+8
Answer: The expressions 2,3,4 and 5 are equivalents.
