your endpoints are correct, however recall that x² means (x)².

<h3>
Answer: approximately 7.7161 US tons</h3>
Work Shown:
1 metric ton = 1.1023 US tons
7*(1 metric ton) = 7*(1.1023 US tons)
7 metric tons = 7.7161 US tons
Answer:
6 miles per hour I think
Step-by-step explanation:
Answer:
the perimeter is 30
Step-by-step explanation:
ok so lets say this
width= x
length= 2x
the area is
A= wl
or
25 = x(2x)
25= 2x^2
5 = x thats the width so we know that if we double that we get the legnth so
the legnth is 10
the perimeter is defined as:
2l +2w =p
insert the width and legnth
2(5) + 2(10) = p
10+ 20= p
p= 30
