2/8 and 4/16 are equivalent to 1/4
1.) X=-2
2.) 2x-y+4=0
Hope this helps! :))
Answer:
average acceleration a=change in velocity / time it took to get to velocity
a=(45-0)mph / 2s = 22.5 mph/hr/s

Answer:

Step-by-step explanation:



Given:
Length = x + x + 3 = 2x + 3
Width = 2 + x
Area = length * width
91 ft² = (2x + 3) (2+x)
91 = 4x + 2x² + 6 + 3x
0 = 2x² + 7x + 6 - 91
0 = 2x² + 7x - 85
(2x + 17) ( x - 5)
x = -17/2 or x = 5
Let x = 5 ;
length = 2x + 3 = 2(5) + 3 = 13
width = 2 + x = 2 + 5 = 7
Area = 13 x 7 = 91
Perimeter = 2(length + width)
Perimeter = 2(13 + 7)
Perimeter = 2(20)
Perimeter = 20 feet of fencing
