Answer: 18/40 and 27/60
Step-by-step explanation:
Multiply the numerator and denominator by whatever number it needs to be multiplied by
9*2 to get 18
20*2 to get 40
9*3 to get 27
20*3 to get 60
Answer:
All real numbers
Step-by-step explanation:
4(x+1) = 4x+4
Distribute
4x+4 = 4x+4
Subtract 4x from each side
4x+4-4x = 4x+4-4x
4=4
This is always true so there are infinite solutions

Answer: Hope this helps!
Step-by-step explanation:
Area of a trapezoid formula base a+base b/2*h
Base a is the top length (22.5)
Base b is the bottom length (49.9)
Add those two lengths together (22.5+49.9=72.4)
Divide that by two (72.4/2=36.2)
Then multiply that by the height (36.2*23.8=861.56)
So your area is 861.56
