The slope of a line is constant because the acceleration is equal to zero.
The slope of a line is always just (y2-y1)/(x2-x1), so in this case:
m=(-7-6)/(4--6)
m=-13/10
m=-1.3
-- The square of the shortest side . . . 16² = 256
-- The square of the medium side . . . 30² = 900
-- Their sum . . . (256 + 900) = <u>1,156</u>
-- The square of the longest side = 35² = <u>1,225</u>
1,156 and 1,225 are not equal, so these 3 numbers

Answer:
5 feet
Step-by-step explanation:
P = 2(w + l)
P = 34
l = w + 7
34 = 2 (w + w + 7)
34 = 2w + 2w + 14
34 - 14 = 4w
20 = 4w
w = 5 feet
Since l = w + 7
l = 5 + 7
l = 12 feet
