Area of paralellogram=legnth times height
l=legnth
h=height
area=96
lh=96
h is 4 less than l
h=-4+l
sub
l(-4+l)=96
-4l+l^2=96
minus 96 both sides
l^2-4l-96=0
factor
(l-12)(x+8)=0
set to zero
l-12=0
l=12
l+8=0
l=-8, imossible, legnth cannot be negative, disreagard this soultion
legnth=12cm
2,3,5,9,17 what’s the pattern?
The pattern is multiply by 2 then subtract 1
2 x 2 - 1 = 4 - 1 = 3
3 x 2 - 1 = 6 - 1 = 5
5 x 2 - 1 = 10 - 1 = 9
9 x 2 - 1 = 18 - 1 = 17
17 x 2 - 1 = 34 - 1 = 33
33 x 2 - 1 = 66 - 1 = 65
65 x 2 - 1 = 130 - 1 = 129

Answer:
x = 4
Step-by-step explanation:
The parallel lines divide the sides proportionally, so ratios of corresponding sides are the same.
(x +5)/15 = (5x +1)/35
Multiplying by 105, we have ...
7(x +5) = 3(5x +1)
7x +35 = 15x +3 . . . . . eliminate parentheses
32 = 8x . . . . . . . . . subtract 7x+3 from both sides
4 = x . . . . . . . . divide by 8

Answer:
187.5 feet
Step-by-step explanation:
we know that
Max's bike moves 25 feet after two rotations
so
using proportion
Find out how many feet will the bike move after 15 rotations
Let
x ----> the distance in feet
