See answers below
Step-by-step explanation:
Perimeter of a square = 4L
L sis the side length of the square
L = 5x^4y^2
perimeter = 4(5x^4y^2)
perimeter = 20x^4y^2
2) Length = 6x-10
Width = 4x+3
Area of rectangle = Length * Width
Area of rectangle = (6x-10)(4x+3)
Area of rectangle = 24x^2+18x-40x-30
Area of rectangle= 24x^2-22x-30
perimeter = 2(L+W)
perimeter 2(6x-10+4x+3)
perimeter = 2(10x-7)
perimeter = 20x-14
Hence the perimeter of the rectangle is 20x-14
Sound waves travel from the outer ear and in through the auditory canal, causing the eardrum to vibrate. This in turn causes three small bones in the middle ear to move. The vibrations move through the fluid in the cochlea in the inner ear, stimulating thousands of tiny hair cells.

Answer:Gary-18 brother-10
Step-by-step explanatiation:Gary=8 years+ brother's years
6 years ago :
Gary=3×brother's years
So:
1st case:brother=1 year,gary=3 years=>after 6 years brother=7 years,gary=9 years (NO)
2nd case:brother=2years,gary=6 years=>after 6 years brother=8 years,gary=12 (no)
3rd case:brother=3 years,gary=9 years=>after 6 years:brother=9 yrs, gary=15 yrs(no)
4th case:brother=4 yrs,gary=12 yrs=>after 6 years: brother=10 years,gary=18 years (This is the one)
Answer: 69
Step-by-step explanation: Percent multiplied by the total number of students: 8/100 x 75 = 600/100. (remember it is 8/100 because it’s 8%.)
Then you simplify which will then get you 6.
Afterwards you need to subtract those 6 students from the group of 75. 75-6=69. So, 69 students.
