5/20 students in Alessandro's class live in Oakdale, which can be simplified to 1/4. 1/4 in decimal form is 0.25. Now to convert it to a percentage, you just multiply that by 100. So 25% of students in Alessandro's class live in Oakdale.

Second Image.
Scale Factor 2
Length = 6
Width = 8
Perimeter = 2(6+8)= 2(14) = 28
Area = 6 times 8 = 48.
Scale Factor 3
Length = 8
Width = 10
Perimeter = 2(8+10)= 2(18) = 36
Area = 8 times 10 = 80.
Scale Factor 4
Length = 10
Width = 12
Perimeter = 2(10+12)= 2(22) = 44
Area = 10 times 12 = 120.

Step-by-step explanation:
Answer:
= 
−7x−20
Step-by-step explanation:
(2x−5)(3x+4)
= (2x+−5)(3x+4)
= (2x)(3x)+(2x)(4)+(−5)(3x)+(−5)(4)
= +8x−15x−20
= −7x−20
