The perimeter of a quadrilateral (four-sided polygon) is 41 inches. The longest side is twice as long as the shortest side. The
other two sides are equally long and are 3 inches longer than the shortest side. Find the length of all four sides.
1 answer:
Answer:
The length of all four sides of a quadrilateral are 7 inches, 14 inches, 10 inches, 10 inches
Step-by-step explanation:
Let the shortest side be
As per given information longest side =
and other 2 sides are equal in length but 3 more times that shortest side =
Perimeter of Quadrilateral = 41 inches given
But perimeter of quadrilateral = sum of all sides
Shortest side =
Longest side =
Other 2 sides =

Answer:
fg(4) = 6
Step-by-step explanation:
f(x) = -x + 7
g(x) = x - 3
fg(x) = -(x-3) + 7
= -x + 3 + 7
fg(4) = -4 + 10
= 6
Answer:
0.1
Step-by-step explanation:
<span>120/x - 120/(x+10) = 1
120x + 1200 - 120x = x(x+10)
1200 = x^2+10x
x^2 + 10x - 1200 = 0
(x+40)(x-30) = 0
Positive solution:
x = 30 km/hr (rate on the 1st trip)
x+10 = 40 km/hr (rate on the return trip)</span>
Jared and Nicole are correct
Subtract 7x on both sides of the equal sign (it'll cancel out) then -3=-3 which makes a true statement.
