Answer:

540m^3

Step-by-step explanation:

find volume of top + volume of bottom

bottom: l*w*h = 16*5*4 =300 m^3

top = area of side times width = area of triangle times width

area of triangle is 1/2*b*h = (6*16)/2 = 48 m^2

multiply by width = 48*5=240m^3

add top and bottom = 300+240=540m^3

8x+21=3 need the answer please

GarryVolchara [31]

Answer:

$x=-\frac{9}{4}$

Step-by-step explanation:

<u>Step 1: Subtract 21 from both sides</u>

$8x + 21 = 3$

$8x + 21 - 21 = 3 - 21$

$8x = -18$

<u>Step 2: Divide 8 from both sides</u>

$8x = -18$

$\frac{8x}{8}=-\frac{18}{8}$

$x=-\frac{9}{4}$

Answer: $x=-\frac{9}{4}$
