Step-by-step explanation:
Since they falls 108 feet in 3 seconds the amount they would fall in one second would be 108/3. 108/3=36
Answer:
151.5 cm^2
Step-by-step explanation:
lets cut stright acrros so you have a triangle 13 (base) by 3 cm (high)
area of a triangle is 1/2 base times hight --> 13x3/2 = 19.5cm^2
now lets doi the rectangle that is 12 by 11
Length times hight is the area is 132
add both areas 132 + 19.5
(X+4)^2-15
This is the answer
12=5x-13x-44
combine like terms
12 = -8x -44
add 44 to each side
12+44 = -8x
56= -8x
divide by -8 on each side
56/-8 = x
-7 =x
