Answer:
V = 1184ft³
Step-by-step explanation:
Volume for Cube
we multiple l*w*h
4x4x4 = 64ft*3 area
Volume for rectangle
we multiple length of the rectangle side first with h
Surface area rectangle = 16 x 7 = 112ft ^2 (=70+42)
Then we multiply it with width 112 x 10 = 1120ft^3
Then we add together the cube V total + Rectangle V total.
64 + 1120= 1184ft^3
Cost of 3 gallons of milk =3.79
Amount Kari paid =20
difference =20-3.79 = 16.21
so she will receive 16.21 back
Answer:
3(x + 1)(3 - x).
Step-by-step explanation:
(x + 3)^2 - 4x^2
Using the identity a^2 - b^2 = (a - b)(a + b), we have
(x + 3 - 2x)(x + 3 + 2x)
= (-x + 3)(3x + 3)
= 3(x + 1)(3 - x)
