Answer:
3 11/20
Step-by-step explanation:
Total gallons of water=7
Spring water=two and one-fourth gallon=2 1/4
Filtered water=one and one-fifth
=1 1/5
Spring water+filtered water=2 1/4 + 1 1/5
=9/4+6/5
= 45+24/20
=69/20
=3 9/20
How many gallons of water were not spring or filtered
=Total gallons- (spring+ filtered water)
=7-69/20
=140-69/20
=71/20
=3 11/20
Answer:
Step-by-step explanation:
Area of rectangle = length * width
Area of rectangle = 55x⁶ + 22x⁴
= 5*11*x⁶ + 2 *11*x⁴
= 11x⁴*(5x² + 2)
width = 11x⁴
So, length = 5x² + 2
